Comment 1 caulier.gilles 2010-03-01 14:40:05 UTC 
I think it's not relevant of libpgf but KDirWatch for KDECore API which have a bug in KDE 4.4.0. It's fixed in current KDE4 implementation from svn trunk (next KDE 4.1)

Dario can confirm that...

Note : try to save to another format and look if it crash also. Typicially, KDirwatch detect new files created in collection and... run an exception...

Comment 2 caulier.gilles 2010-04-04 10:46:42 UTC 
digiKam and Kipi-plugins 1.2.0 are out. Please check if crash is still valid there.

Thanks in advance

Comment 3 Laurent Espitallier 2010-04-04 17:59:52 UTC 
Tested this afternoon, no problem with openSUSE 11.2, KDE SC 4.4.2 and digiKam 1.2

To me it is fixed.
