Bug 289725

Application: digikam (2.4.1)
KDE Platform Version: 4.7.95 (4.8 RC1 (4.7.95)
Qt Version: 4.7.4
Operating System: Linux 3.1.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:

I have reproduced the problem twice : When I upload only one photo on Picasa, Digikam crashes.

I tested few days ago and it worked fine but I usually upload several photos and I have upgraded my KDE 4.8rc1 (I don't know if there is a link)

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
