Description Nate Graham 2022-04-07 15:57:58 UTC 
Application: plasmashell (5.24.80)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.93.0
Operating System: Linux 5.16.16-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.24.80 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I don't know if this is related, but I received a large number of notifications from NeoChat due to an active and fast-paced conversation, and plasma crashed. Other than that, the crash seemed quite random. I was not actively interacting with Plasma at the time.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
