Package: mc Version: 3:4.8.33-1 Severity: important The recent mc upgrade appears to have introduced a major regression in behaviour of the command line subshell. I'm referring to the single-line command line appearing near the bottom of the normal mc screen below the list of files, not the full subshell accessed via Ctrl-o. The use-context is running mc from bash shells in Gnome terminals.
The command line becomes unresponsive after being used to launch an app (e.g. launching emacs or libreoffice to edit a file). Normally the command line can be used to navigate over the directories and file list, with the arrow keys moving the cursor to select a given file. A command can be typed in and executed by pressing Enter. The problem seems to be easily reproducible upon launching a command in the background (e.g. typing `emacs &` in the command line to launch emacs, with & running it in the background). mc seems to retain functionality temporarily if & is not used (i.e. running a command in the foreground), and temporarily stable after Ctrl-z and bg is used to send the command to background. But eventually the unresponsiveness starts anyway. When the command line becomes unresponsive, the cursor no longer moves with the arrow key. Instead, the arrow key cycles through previous commands, like Ctrl-p. The Enter key is ignored, so commands can no longer be executed. Ctrl-o and Ctrl-u still work normally. The problem is exacerbated since the problem does not simply affect one window (one Gnome terminal). All windows (all mc instances) become equally unresponsive once the problem has started. Worse, the problem is persistent, continuing even after all terminals have been closed and new ones started. Rebooting seems to be the only way to restore normal behaviour, at least until the bug gets triggered again. The bug is making mc effectively unusable. -- System Information: Debian Release: trixie/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.12.13-amd64 (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE=en_AU:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages mc depends on: ii libc6 2.40-7 ii libext2fs2t64 1.47.2-1 ii libglib2.0-0t64 2.83.3-2 ii libgpm2 1.20.7-11+b2 ii libslang2 2.3.3-5+b2 ii libssh2-1t64 1.11.1-1 ii mc-data 3:4.8.33-1 Versions of packages mc recommends: ii mailcap 3.74 ii perl 5.40.1-2 ii sensible-utils 0.0.24 ii unzip 6.0-28 Versions of packages mc suggests: ii 7zip [p7zip-full] 24.09+dfsg-4 ii antiword 0.37-16 pn arc | arcanist <none> pn arj <none> ii binutils 2.44-1 ii bzip2 1.0.8-6 ii cabextract 1.11-2 pn catdoc <none> ii cpio 2.15+dfsg-2 pn ctorrent <none> pn dbview <none> ii default-jdk-headless 2:1.21-76 pn djview4 <none> ii djvulibre-bin 3.5.28-2+b2 pn elinks <none> pn epub-utils | ncbi-entrez-direct <none> ii evince [pdf-viewer] 46.3.1-1+b1 ii exif 0.6.22-4 ii file 1:5.45-3+b1 ii genisoimage 9:1.1.11-4 ii gettext 0.23.1-1 ii ghostscript 10.04.0~dfsg-2+b1 pn glade <none> pn gputils <none> ii groff-base 1.23.0-7 pn gv <none> ii imagemagick 8:7.1.1.43+dfsg1-1 ii imagemagick-7.q16 [imagemagick] 8:7.1.1.43+dfsg1-1 ii info 7.1.1-1+b1 pn jlha-utils | lhasa <none> pn kchmviewer <none> pn libaspell-dev <none> ii libbatik-java 1.18+dfsg-2 pn libchm-bin <none> pn liblz4-tool <none> ii libxml2-utils 2.12.7+dfsg+really2.9.14-0.2+b1 pn links2 <none> ii lynx 2.9.2-1 pn lyx <none> ii lzip 1.25-1 ii man-db 2.13.0-1 pn mikmod <none> pn mpg321 <none> pn mplayer <none> ii odt2txt 0.5-7 ii okular [pdf-viewer] 4:24.12.2-1 ii p7zip-full 16.02+transitional.1 pn par2 <none> pn poedit | potool <none> ii poppler-utils 25.01.0-4 pn procyon-decompiler <none> ii python3 3.13.1-2 pn python3-boto <none> ii python3-tz 2025.1-3 pn rar <none> pn rpm <none> pn sox <none> ii sqlite3 3.46.1-1 ii texlive-binaries 2024.20240313.70630+ds-5+b1 pn timidity <none> pn unace | unace-nonfree <none> pn unalz <none> pn unar <none> ii unrar 1:7.1.3-1 pn vorbis-tools <none> ii w3m 0.5.3+git20230121-2.1 pn wimtools <none> pn wv <none> ii xpdf [pdf-viewer] 3.04+git20250103-1+b1 pn xpmutils <none> ii xz-utils 5.6.3-1+b1 ii zip 3.0-14 ii zstd 1.5.6+dfsg-2 -- no debconf information
