Public bug reported:
Digikam 3.3.0 from the backports PPA for Kubuntu 13.04 (apt-cache policy
info at the end).
It seems really slow compared to previous versions, perf top shows it
spending ~10% of its time in KLocalePrivate::encodeFileNameUTF8. When
you check with strace it seems to be spending most of its time looking
for icons that don't exist:
