All crashes with this signature on Fennec over the past 4 weeks are on Fennec 4. However, we are still seeing this signature on Firefox 8 and 9 on Windows.

I am closing this bug since there are no crash reports beyond Fennec 36. Please reopen this bug report if you can reproduce this crash in a current Fennec build.
