Sentry Crash Report:

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

Thank you for reporting this issue. I will look into it shortly.
Comment 2 Alexander Reinholdt 2020-04-12 15:42:19 UTC 
Git commit 560432348befec911869e484a3f04a58e20bc811 by Alexander Reinholdt.
Committed on 12/04/2020 at 15:39.
Pushed by areinholdt into branch 'master'.

Fixed several issues and crashes.

The crashes that occurred when remounting shares has been eliminated.

The notification of the user after a mount or unmount has been fixed.

The unmounting of shares when the system went offline has been fixed. For this to work,
you also need the improved mount helper.
