Bug 461605

Application: plasmashell (5.25.5)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.15.0-52-generic x86_64
Windowing System: X11
Distribution: Feren OS
DrKonqi: 5.25.5 [CoredumpBackend]

-- Information about the crash:
After logging in, Plasma crashed, which happens lots of times on my machine. But this time it did not recover automatically. Instead, a second crash happened, which is this one.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
