use this to reproduce issue
SUMMARY
Pretty much the title. If the Exec= file of a .desktop file contains ' at the
start and end, AND the application contains switches (--example), plasmashell
will segfault when trying to edit them (right click, "edit application") from
the kickoff menu.
I haven't been able to get debug logs yet, but so far two people I know have
been able to reproduce this issue. A file is attached to this bug report which
should reproduce it.
The main issue here is that that "Edit Application" dialog is what added the
single commas to the start and end of the Exec line, therefore making it
possible for someone to make an application invalid and be unable to edit it if
they're unaware of the location of the desktop file on the filesystem (this
could be a separate bug, let me know)
STEPS TO REPRODUCE
1. Create a .desktop file with an Exec line that starts and ends on a single
comma (') and that contains command line switches (--example)
2. Open kickoff, search the malformed .desktop file and right click it,
selecting Edit Application
OBSERVED RESULT
plasmashell segfaults
EXPECTED RESULT
no crash occurs, instead plasmashell should let
