Package: libcairo2
Version: 1.10.2-2
Severity: important

Hello,

upgrading libcairo2 to 1.10.2-2 crashes Xorg on a VIA VX800 Chrome 9
driven by openchrome when starting firefox (iceweasel) or gdm3 (it gets
it managed to display the greeter and the bottom panel and crashes
then).
Xorg log excerpt:
	Backtrace:

	Segmentation fault at address 0xc

	Fatal server error:
	Caught signal 11 (Segmentation fault). Server aborting

Downgrading libcairo2 to 1.8.10-6 solves the issue: No crashes.
This issue doesn't show up on a machine with Intel G35 driven by intel.

I can't really tell how deep libcairo2 is involved into this, since
upgrading to 1.10.2-2 also installs:
	libdrm-nouveau1a 2.4.23-0.0
	libegl1-mesa 7.10-3
	libegl1-mesa-drivers 7.10-3
	libxcb-dri2-0 1.7-2
	libxcb-shape0 1.7-2
	libxcb-xfixes0 1.7-2
However, I have no idea how to narrow the issue down to one of them.


regards
   Mario

This was fixed a while ago.  Closing.
