Bug 157149

Crash appears in Timeline...

I will take a look

Gilles Caulier

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

Gilles Caulier

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.

I'm still not able to reproduce the crash on my computer...

Marcel, do you can see the problem ???

Gilles

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 ?

Don't access QMap::begin() if map is empty.
