Sentry Crash Report:

Description Gianni 2018-03-18 10:45:53 UTC 
Application: plasmashell (5.12.3)

Qt Version: 5.10.0
Frameworks Version: 5.44.0
Operating System: Linux 4.13.0-37-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
Plasmashell crashed while I was writing a command on dolphin's console (I was just writing rm something, it crashed when I typed in the first letter). I dont know if it's really correlated, but I wasnt doing anything else. It's possible that I didn't have the focus on the console, in that case I would have typed the letter "r".. somewhere that plasma didn't like.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Are you able to reproduce this in Plasma 5.17 or the upcoming 5.18?

> Are you able to reproduce this in Plasma 5.17 or the upcoming 5.18?

I am unable to reproduce this issue at all, I sent this bug via DrKonqi kind of unaware of how it worked back then. I think this bug can be safely closed, since I never experienced such crash ever again.
Comment 3 Christoph Feck 2020-02-13 14:13:03 UTC 
Thanks for the update; changing status.
