            Bug ID: 493568
           Summary: Using the RMB menu "Open with..." action always fails
                    to launch the app with an error dialog, when clicking
                    on text that ends in a colon
    Classification: Applications
           Product: konsole
           Version: master
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general

  Target Milestone: ---

Running Neon noble unstable, with Konsole package version
4:24.08.1+p24.04+vunstable+git20240922.1531-0. Konsole identifies itself as
version 24.11.70

SUMMARY
When the terminal shows a list of files with colons at the end of them (as is
common for output from `git grep` or just `grep` with various options) when
right clicking a file path in the terminal output and choosing "Open with..."
from the menu (or "Open With" -> "Other application"), the XDG portal "Choose
Application" dialog opens. Then - no matter which application is selected - an
error dialog box appears with the text:

WorkingDirectory= expects an absolute path or '~'

I have reviewed the .desktop files of the applications I'm trying to launch
(most are default installed .desktop files) and none of them have the
`WorkingDirectory` setting.

STEPS TO REPRODUCE
1. Open Konsole
2. Execute the following repro command: ls | sed 's,$,:,'
3. Right click any file name and choose "Open with"
4. In the dialog box that opens, choose any application

OBSERVED RESULT
An error dialog pops up and the file isn't opening

EXPECTED RESULT
The file should be opened with the specific application, or - probably more
correct - the path including the colon will be sent as the argument to the
application that will likely show its own error.

SOFTWARE/OS VERSIONS
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 6.1.90
KDE Frameworks Version: 6.7.0
Qt Version: 6.7.2
Kernel Version: 6.8.0-45-generic (64-bit)
Graphics Platform: Wayland
Processors: 20 × 12th Gen Intel® Core™ i7-12700H
Memory: 31.0 GiB of RAM
Graphics Processor: Mesa Intel® Graphics

ADDITIONAL INFORMATION
The problem can be worked around by going into the profile setting, the "Mouse"
section and removing the colon character from the field "Word characters".

I think that having a colon as a word character for mouse selection, by
default, is probably not a good idea, but removing it doesn't fix the problem
that there's a surprising Konsole error dialog if it is set like that.
