[Digikam-users] Albumview freezes - need help debugging

[Christoph Huckle]

Hello,

on my latest  setup with digikam I am experiencing hangs on certain
Albumviews.
I'm running 4.2 on Opensuse 13.1 on an Microsoft Surface Pro 3. All
pictures are on a NAS the database runs on a server as MySQL.

With kdebugdialog enabled and gdb I get the following outputs if I let it
freeze:

this is then the backtrace output:

what else can I do to provide more useful information?
As said it only happens on certain folders.

BR
Chris.
