[Bug 1270571] [NEW] Systemsettings crash when interrupting kcm-language at loading

Fri Feb 21 10:30:54 UTC 2014

You have been subscribed to a public bug:

Crash if I close Systemsettings while kcm-language is loading, see
http://ubuntuone.com/2elkr9n33oAARtr5Bfl0xU. (Triggered in video:
clicked Locale and pressed Alt + F4 immediately.)

Reproducible with Kubuntu 13.10 and latest (01/19/14) Kubuntu 14.04
daily iso.

Initially this was reported here:
https://bugs.kde.org/show_bug.cgi?id=329329 but Christoph Feck could not
reproduce it and I was also unsuccessful reproducing it using Opensuse
13.1 (same KDE version), so this seems to be Kubuntu specific.
