9 crash reports from a user on the same Nexus 7 on trunk

Shoot, maybe this is also a regression from bug 1004850. Setting the dependency just in case. I'll investigate.

Not entirely sure whether or not this is related to bug 1004850. A regression window would be useful here.

Prior, we need steps to reproduce. Nonetheless you can take a peak at the first report, and yes it's from that timeframe.

I suspect this is just another symptom of bug 1030141. Possible steps to reproduce:

1. Install a nightly built before bug 1004850 landed with a fresh profile.
2. Disable all built-in panels in Settings -> Customize -> Home.
3. about:home will only show the Firefox watermark now.
4. Install new nightly with this fix included.
5. Fennec will crash on next startup.

This is very likely fixed by the patch bug 1029046. Please verify with the STR in comment #5. This bug is tablet-specific btw.
