Description dasfreak 2020-04-05 05:18:59 UTC 
Application: smb4k (3.0.3)

Qt Version: 5.14.1
Frameworks Version: 5.68.0
Operating System: Linux 5.3.0-40-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:

Resumed from standby. I had recently changed SMB server password so SMB4k came back from standby asking for share password to be re-entered. Entered correct password and app crashed.
Note these shares are bookmarked and set to auto-remount.

-- Backtrace:
Application: Smb4K (smb4k), signal: Segmentation fault
