How reproducible:
It happens randomly, I have to run it cca. 5-times before it's stable. The client is connecting to a MUC automatically, but I am not sure if it's the reason. For a brief moment the app is displayed, it connects to MUC, but it crashes instantly.


Steps to Reproduce:
1. Run psi-plus
2. It crashes randomly
3.

Actual results:
$ psi-plus

Expected results:
It should not crash.

Additional info:

Comment 1 Kevin Kofler 2018-05-06 22:19:05 UTC

This backtrace looks like it is calling a slot of an already deleted object. Use Valgrind to find where the object is being deleted, that delete needs to be changed to a deleteLater.

Comment 2 Michal Špondr 2018-05-07 13:33:04 UTC

I am not able to reproduce it with Valgrind.

Comment 3 Michal Špondr 2018-05-16 06:49:14 UTC

I've found out the crashing stopped after I removed OpenPGP keys from jabber account.
