Not really.  Exactly this behavior has been reported before, but it always 
fails mysteriously in some X code related to strings / fonts.  It could be an 
X problem, a fontserver problem or a threading problem.  If it is a threading 
problem Nils may have solved it by chance (code only in CVS at this point).  
So far, nobody with the skills to investigate deeper has been able to 
reproduce it.  I've never had it happen on any of my machines, and it seems 
to be clearly dependent on more than just GNUnet.  If you can figure out 
more, that'd be great, but I can't even tell you where best to begin at this 
point (short of trying CVS and checking if the problem disappears).
