Public bug reported: I'm trying to load a 32bit application (Firefox 3 from mozilla.org) on amd64 Hardy, and I'm getting the error:
Gtk-WARNING **: Error loading theme icon 'gtk-ok' for stock: Unable to load image-loading module: /usr/lib/gtk-2.0/2.10.0/loaders /libpixbufloader-png.so: /usr/lib/gtk-2.0/2.10.0/loaders /libpixbufloader-png.so: wrong ELF class: ELFCLASS64 This has been reported in https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/177869 for instance. This worked on gutsy, the regression seems to be related to this Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=439004 [ Josselin Mouette ] * 020_immodules-files-d.patch, 021_loader-files-d.patch: read the GDK_PIXBUF_MODULE_FILE and GTK_IM_MODULE_FILE variables before the Debian directories. Thanks Thadeu Lima de Souza Cascardo. Closes: #439004. The issue is that the GtkPixbuf modules loading order changed, so that the 64bit loaders are loaded after the 32bit ones, so it fails. Here's a strace from Gutsy (kept only meaningful calls): 7773 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 21 7773 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d/libgtk2.0-0.loaders", O_RDONLY|O_LARGEFILE) = 22 7773 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d/librsvg2-common.loaders", O_RDONLY|O_LARGEFILE) = 22 7773 open("/etc/gtk-2.0/gdk-pixbuf.loaders.32", O_RDONLY|O_LARGEFILE) = 21 7773 stat64(0x835e328, 0xffe83a2c) = 0 7773 open("/usr/lib32/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so", O_RDONLY) = 21 <-- OK: we're loading the 32bit module Strace from Hardy: 19698 open("/etc/gtk-2.0/gdk-pixbuf.loaders.32", O_RDONLY|O_LARGEFILE) = 21 19698 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|0x80000) = 21 19698 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d/libwmf0.2-7.loaders", O_RDONLY|O_LARGEFILE) = 22 19698 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d/libgtk2.0-0.loaders", O_RDONLY|O_LARGEFILE) = 22 19698 open("/usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d/librsvg2-common.loaders", O_RDONLY|O_LARGEFILE) = 22 19698 open("/usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so", O_RDONLY) = 21 <-- ISSUE HERE: the 64bit module is read, which will fail to load with a 32bit binary. I think one good way to solve this issue may be to first look if directory /usr/lib32/gtk-2.0/2.10.0/loaders exists, and use that instead of PIXBUF_LIBDIR for the gdkpixbuf_module_files_d_str variable (021_loader-files-d.patch). (The other quick and dirty way would be to revert the Debian patch. Unfortunately this also reverts the issue that the reporter was having, but this issue here may be more important for Hardy users of 32bit software on amd64). ** Affects: gtk+2.0 (Ubuntu) Importance: Undecided Status: New -- 32bit GdkPixbuf modules not loaded when using ia32-libs https://bugs.launchpad.net/bugs/205223 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
