Can consistently hit this multiple times with just doing '$ monkey -p org.mozilla.fennec -v 3000'

I don't think I have this monkey fuzzing tool... where do I get it? Also, can you watch Fennec in action while this is happening? Maybe that would give some hint as to manual steps to reproduce.

$ adb shell monkey -p org.mozilla.fennec -v <number> - where number is the number of pseudo-random number of events to send the the package supplied on command line.

You can watch but it's really fast and random each time.

If you click the crash report and go to reports it looks like I'm not the only one hitting this so far. It is low volume though.

I've reproduced this crash 14 times in an hour interval, performing monkey testing on a Motorola RAZR XT910 (Android 2.3.5) / Aurora 26.0a2 (2013-10-03)
