This is with dolphin 15.12.2 (but it also happens with 15.12.1 and 15.12.0), Qt
5.5.1 and KDE Frameworks 5.19.0.
Reproducible: Always
Steps to Reproduce:
1. run e.g. "dolphin --icon system-file-manager"
2. close dolphin
Actual Results:
Dolphin crashes with the mentioned backtrace.
Expected Results:
Dolphin should exit cleanly.
I cannot reproduce the crash with any other KF5 application, so it seems to be
something specific to dolphin.
Downgrading KDE Frameworks to 5.16.0 eliminates the crash, so it seems to be
caused by some change in Frameworks between 5.16.0 and 5.19.0.
http://bugzilla.opensuse.org/show_bug.cgi?id=965514 would suggest it started
with 5.18.0.
Only downgrading kiconthemes does not help though.
I'll try to find out which change exactly causes this.
