Bug#611159: "surf http://sydneypadua.com/2dgoggles/" segfaults in WebCore::ImageBuffer::context

[Jonathan Nieder]

Package: surf
Version: 0.4.1-4

Hi Gustavo, Kai, et al,

Typical experimental i386 system.  Reproducible crash today:

 $ gdb --args surf http://sydneypadua.com/2dgoggles/
 [New Thread 0xa2dfdb70 (LWP 2663)]
 [New Thread 0xa25fcb70 (LWP 2664)]

 Program received signal SIGSEGV, Segmentation fault.
 WebCore::ImageBuffer::context (this=0xbffff1b0) at ../WebCore/platform/graphics/cairo/ImageBufferCairo.cpp:95
 95      ../WebCore/platform/graphics/cairo/ImageBufferCairo.cpp: No such file or directory.
         in ../WebCore/platform/graphics/cairo/ImageBufferCairo.cpp

The window had opened, but nothing rendered yet (red bar ~40% across).

Backtrace attached.  Known problem?  Any hints for debugging?

Thanks for webkit. :)
Jonathan
