kde_at_, has already found the problem. 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_at_ :). 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.
