Comment 1 Laurent Montel 2017-10-16 13:13:14 UTC 
Could you test if another kde apps crash when you edit toolbar ?
It seems wierd that it's kmail specific
Comment 2 Andrius Štikonas 2017-10-16 13:14:51 UTC 
Well, as I've  said in the bug report, I have already tried.

Dolphin, KDevelop, Krusader didn't crash.

I know it is strange... Not sure why it only happened with KMail
Comment 3 Justin Zobel 2020-12-17 05:31:13 UTC 
Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Comment 4 Andrius Štikonas 2020-12-17 12:29:33 UTC 
I can't reproduce this anymore.
