Bug ID: 503830
Summary: Reproducible crash in Digital Clock Time Zomes config
page
Classification: Plasma
Product: plasmashell
Version: master
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Digital Clock widget
Assignee: plasma-b...@kde.org
Reporter: cwo....@posteo.net
Target Milestone: 1.0
SUMMARY
Using the steps below, I can reproducibly get plasmashell to crash on two
different computers using master. I've gone back to commits from February (when
the new Time Zones selector was added) and can reproduce it there (also
required going back for several other components, at least libplasma) so it's
likely not related to other changes since then. DrKonqui fails at creating a
backtrace for me, but I got one from running plasmashell in gdb, see below
(still some missing symbols though)
STEPS TO REPRODUCE
1. Open Digital Clock Time Zones config page
2. Click Add Time Zone
3. Select a different config page (e.g. Shortcuts) in the dialog
4. Select Time Zones again
OBSERVED RESULT
Crash
EXPECTED RESULT
No crash, Time Zones config page is selected again.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 42
KDE Plasma Version: master
KDE Frameworks Version: master
Qt Version: 6.9.0 (both stock Fedora and my self-compiled kde-builder version)
