Thanks for the bug report. This crash cannot occur anymore in KDE 4.10 because Dolphin's Information Panel does not use the KFileMeta* classes from kdelibs anymore then (unless it is built without Nepomuk headers, but given that the KFileMeta* classes are essentially unmaintained, it seems unlikely that this issue will get addressed). *** This bug has been marked as a duplicate of bug 313792 ***
