Oups, the patch is in the wrong way. You should use '-R' with patch ...

Excuse me, it was my first patch.

Bye, Haypo

I received a mad "SIGSEGV" while I would like to start the game Wormux
(I'm working on porting it to ClanLib 0.7).

(gdb) backtrace

I understood that I need to open a window before loading first font (from XML resource file). I can correct this bug in my game, but I think that ClanLib should test somewhere :
  assert (CL_DisplayTarget::current != NULL);
