Dear Debian Team,
I think I found a bug, and I'm writing to this list as I don't know the
associated package (according to https://www.debian.org/Bugs/Reporting).
I'm experiencing this bug in konsole (KDE's terminal emulator), but the
same bug has been reported here
https://askubuntu.com/q/1331111
in xfce-terminal on Ubuntu 20.04, so I don't think it is a konsole or a
KDE bug. Maybe the affected package is bash-autocompletion, but I don't
know for sure.
I would like to run okular opening the pdf file
~/dir1\ with\ blanks/dir2/file.pdf
via command line. In konsole I type
okular ~/dir1\ with\ blanks/
and hit the tab key twice for autocomplete. But I won't get offered
dir2. After adding more letters like
okular ~/dir1\ with\ blanks/di
to make the completion to dir2 unique, nothing happens at all after
hitting tab (twice). Only after spelling out the complete directory as
okular ~/dir1\ with\ blanks/dir2
and then hitting tab, autocomplete works again as expected.
My feeling is that there are two components which together trigger this bug.
(1) Blanks in the path.
The blanks in dir1\ with\ blanks, because renaming it to something
without a blank like dir1 makes the problem disappear. Also, note that
adding a blank to dir2 is not a problem.
(2) Automatic filtering of autocompletion candidates.
Starting the command with 'konsole' and then hitting tab will only
complete to pdf files. When I do the same with 'ls' instead of 'okular',
no filtering takes place, and the above problem disappears (meaning that
typing
ls ~/dir1\ with\ blanks/
and hitting TAB twice will offer me dir2.
Relevant packages:
I'm on Debian 12 (stable) amd64.
konsole 4:22.12.3-1
bash 5.2.15-2+b2
bash-completion 1:2.11-6

Thank you.
