Comment 1 vandalhj 2021-08-09 06:55:51 UTC 
It was present in earlier versions too, i think 0.9.8 and 0.9.9 or something (the two versions before 0.10.0)
Comment 2 Michail Vourlakos 2021-08-09 09:06:39 UTC 
there was one of such crash fixed in upcoming next bug release.

Comment 3 vandalhj 2021-08-09 09:52:46 UTC 
Clearing cache helped for one restart, on next one the bug persisted. Using ddd looks hard, as i would have to start ddd and execute run backtrace before latte-dock - and it's startup crash.I set up env, does it persist over startup ?
Comment 4 vandalhj 2021-08-09 10:01:31 UTC 
On default dock the crash also persist. As earlier, removing QT cache prevent next startup crash.
Comment 5 Michail Vourlakos 2021-08-09 10:03:14 UTC 
Without detailed backtrace having a traceable fault is not possible.
