Hi! Meanwhile I upgraded my PC to a Pentium Q6600 and one of the new Radeonhd cards. The problem still exists, but now the system is strong enoguh to live through it. also I could get a full backtrace with all symbol infos. After killing digikam, the system returns to normal state within 10 seconds, without killling digikam, the X server remains unresponsive, but not completely dead. Regards, David -- The primary freedom of open source is not the freedom from cost, but the free- dom to shape software to do what you want. This freedom is /never/ exercised without cost, but is available /at all/ only by accepting the very different costs associated with open source, costs not in money, but in time and effort. -- http://www.schierer.org/~luke/log/20070710-1129/on-forks-and-forking
