Hi, The problem is in cairo directfb backend. It's broken in versions newer than 1.10.2. AFAIR in this case it triggers some kind of infinite recursion which ends up with SIGSEGV due to running out of stack. It's relatively simple to fix it and get rid of the crash, but you won't see anything on the screen due to more stuff being unimplemented. Some time ago I've started working on getting current caito master usable with dfb, but due to lack of time I havent finished it yet. If you want I can push my current work branch to github. If you dont feel like fixing cairo than downgrading to 1.10.2 is also an option.
