Comment 1 Martin Klapetek 2015-09-23 15:19:23 UTC 
Thanks for the report

Can you please tell me which KAccounts version you have installed?

Furthermore, is this crash reproducible? Ie. does it happen every time?

And finally, can you please install kde-config-telepathy-accounts-dbg package and post new backtrace? It's enough if you paste just the thread with [KCrash Handler] on top (usually Thread 1)
Comment 2 Eugene 2015-09-23 17:58:10 UTC 
I have installed kaccounts 15.08.1. Crash happens every time but only if I first push "+" button, then ICQ button, then "cancel" button and then choose any of existing ICQ accounts and push "Configure" button. Crash happens all the time in that case.
I've installed kde-config-telepathy-accounts-dbg package but how to get backtrace now? KCrash Handler not starts when crash happens.
Comment 3 Martin Klapetek 2015-09-23 18:25:26 UTC 
> Crash Handler not starts when crash happens.

Hmm...and you sure it's crashing?
Comment 4 Eugene 2015-09-23 19:32:06 UTC 
Tell me what it is: https://youtu.be/XqE7k45FMmc . May be I'm wrong but when some window closes on pushing Configure button this looks like some kind of crash for me.
Comment 5 Martin Klapetek 2015-09-23 19:50:43 UTC 
Ok, I can reproduce, here's a backtrace:

How did you get backtrace?
Comment 7 Martin Klapetek 2015-09-23 20:26:40 UTC 
$ gdb --args kcmshell5 kcm_kaccounts

However, I was running an outdated version, this is fixed in 15.08.2, please test.

I just recently got an update with 15.08.1 at this evening. It seems 15.08.2 is very fresh.
Thanks for gdb example command.
