Turns out konsole will crash in recent -CURRENT (post-15 august) if you have a hostname longer than 16 characters because of a change in gethostname (I guess). Sorry to point at threads@ :). So, to have a working Konsole at this moment with libkse, you have to get Michael's patch and a hostname shorter than 16 characters. Best regards, Arjan
