I confirm the exact same bug that crashed Dolphin for me.

Happened after I navigated to some directory and created new folder using
dolphin in there.
My kdelibs is built with inotify support and I guess it's what triggered this
crash within kdelibs code just after new directory (successfully created)
appeared.

This is KDE 4.4 (4.4 branch), Qt4 4.6.1

Application: Dolphin (dolphin), signal: Segmentation fault
