Description Kyle Devir 2019-09-20 07:07:37 UTC 
Application: plasmashell (5.16.90)

Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-arch1-1-custom-5.3 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
Trying to start plasmashell after upgrading to 5.17 Beta results in a near-instant crash.

I tried clearing my ~/.cache, because that's sometimes caused issues in the past.

I noticed this interesting line from the terminal output: "double free or corruption (out)", which happens at the moment of the crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Okay, weirdly, starting a KWin Wayland session seems to have resolved it.

I was getting the crashes on the X11 KWin session, but after it starting working on Wayland, the X11 crashes were also resolved.

I have no idea what happened, but should I mark this as resolved...?

I guess so. :)
