Linux-x86-64 and cairo crash

[Riccardo Mottola]

Hi,

I just updated everything on my linux-x86-64 box, running gcc4 and 
libobjc2 from our own repo. Reconfigured/cleaned/installed all core.

All apps segfault, here Ink:

2011-09-11 23:11:28.803 Ink[30192] Using time zone with absolute offset 0.

Update: the issue is that it is exported to a 15/16bit display perhaps?
I tried exporting to a 24bit display and Ink works fine!

I wonder if it is our bug or cairo's...
