I experience this bug also. Can this be patched in the current version or do we have to wait until the next upstream release?

Hi, the diff in the comment #35 on that bug report is already applied in 2.0.0. Gilles says that "the git version is fixed", but I cannot find the specific commit which fixes this. You could use the workaround in the comment #54 until we fix this.

Thanks. I can confirm launching digikam as follows successfully works around the issue:

$ LD_PRELOAD=/usr/lib/libusb-0.1.so.4 digikam

Somebody has already fixed this issue which comes from libdc1394 :
http://sourceforge.net/tracker/?func=detail&atid=308157&aid=3361405&group_id=8157

I applied the attached patch, then recompiled libdc1394.
The proposed patch definitively fixes the crash :)
