Seems to come from KDE thumbnail service. Which is your kdelibs version? Is this reproducible, does it always happen when you open the import dialog? Does it only happen when you import from a specific folder?
Marcel, This is a crash relevant of Phonon + Xine. Gilles Caulier
I believe the original crash is done in thread 2 inside KServiceTypeTrader::query, where kcrashhandler is called. The apparent crash in thread 1 comes from an xioerror and is secondary. But in neither case it seems to be caused by anything that digikam would do wrong.
Marcel, code relevant of KServiceTypeTrader is here : http://lxr.kde.org/source/extragear/graphics/digikam/utilities/cameragui/umscamera.cpp#276 The goal of this code is to try to get thumb from video files. Gilles
Well this is another of those bugs that will stay open unless we either move it to kdelibs, the reported says it works now for him or we close it in a few months... The code service trader code works for all of us, so I dont see any needed change in this.
Merging to bug 189156 which has uses more recent KDE/digikam and provides a more verbatim backtrace. I still consider this a kdelibs problem. *** This bug has been marked as a duplicate of bug 189156 ***
Fixed with https://bugs.kde.org/show_bug.cgi?id=189156
