Aurelien Jarno made some research about this on the Debian BTS and apparently this seems to be a memory corruption https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754392
For the record, it seems I reproduced something similar on the first try: $ weston --modules=cms-colord.so ...

Can you still reproduce the issue with the weston from git? It looks it was fixed recently: http://lists.freedesktop.org/archives/wayland-devel/2015-July/023510.html
