--- Comment #4 from Victor Dodon <dodonvictor at gmail.com> ---
with the last 2 commits digikam and kxmlkipicmd are crashing when activanting
the action "Configure Digikam" and "Configure kxmlkipicmd" respectively when
there are plugins that must not be loaded. The backtrace:

Application: digiKam (digikam), signal: Segmentation fault
