Comment 1 Michail Vourlakos 2019-08-01 07:30:31 UTC 
Crashes after updates, can happen. Is this reproducable?
Comment 2 Michail Vourlakos 2019-08-01 07:51:00 UTC 
2. Try also to clear the cache when Latte is not running with: latte-dock --cc

3. Where you running Latte from command line when the crash happened?

Comment 4 John H 2019-08-06 22:02:19 UTC 
Latte-dock has not crashed on subsequent updates.
Clearing the cache made no perceptible difference to performance.
I have never run the dock from the command line.
Since the crash the optional Lock / Logout widget no longer works.
The last issue arose simultaneously on "KDE Neon" on this machine and 2 other laptops I own.

The lock/logout issue is fixed with 0.9.1 if you still have problems with it after the update then open a new issue just for that
