Andreas,

I have cleaned libkexiv2 source code and digiKam DMetadata code about no re-entrancy Exiv2 calls. Crash still here at the same place into libkexiv2:

gdb /opt/kde4/bin/digikam --interpreter=mi2 -quiet
Using host libthread_db library "/lib/i686/libthread_db.so.1".
Exited normally(gdb) quitgdb /opt/kde4/bin/digikam --interpreter=mi2 -quiet
Using host libthread_db library "/lib/i686/libthread_db.so.1".
Quit
(gdb) quitquit
The program is running.  Exit anyway? (y or n) [answered Y; input not from terminal]
(gdb) Process exited
gdb /opt/kde4/bin/digikam --interpreter=mi2 -quiet
Using host libthread_db library "/lib/i686/libthread_db.so.1".
