--- Comment #11 from Pavel Ondračka <pavel.ondracka at email.cz> ---
This can be easily reproduced using r300g, softpipe or llvmpipe with this webgl
test:
https://www.khronos.org/registry/webgl/sdk/tests/conformance/misc/type-conversion-test.html
This was tested with firefox 18.0. To test with llvmpipe or softpipe you
probably also need to set webgl.force-enabled=true in about:config, since it
seems they are blacklisted.

Backtrace:

Rest of the backtrace (in libxul.so and firefox) is truncated since I don't
have firefox debug symbols, however it probably doesn't contain anything
interesting. Also no errors in dmesg.
