mangus,

Today Marcel has fixed a bug timeline (discovered in KDE4 port of relevant code).

Can you checkout svn code, and try again ?

Thanks in advance

Ok, I've tried digikam (compiled some days ago) and it crashed with the same backtrace of Mangus.

Now I've recompiled the revision 770899 and it still crash.

FiNex,

we need more informations to debug. Are you few images in your collection or do you start with a clean root album path ?

Also, can you start digiKam under valgrin like it's explained in HACKING file to get more informations about the crash ?

I was having the same bug and I also found that it was coming from the fact
that the QMap was empty.

With the latest commit, it works now.
