Attached is a GDB log session for Firefox after it freezes. It was marginally more difficult to get it to freeze while running
firefox in GDB: I had to wiggle the mouse more. It may have taken 20 seconds.

Sadly, this log session has little useful data in it since Firefox's libraries seem to have practically no symbols, but perhaps it's useful to somebody.

For reference, if someone else wants to reproduce this, you need to run firefox in GDB from either the console or another computer, since this bug will freeze your X11 session, preventing you from, say, using GDB. In either case, you would do this:

1. Go to console/other computer and log into your debug computer.
2. export DISPLAY=:0
3. firefox -g
4. "run"
5. Go back to X11, if you were on the console
6. Repro bug
7
. Go back to console/other computer
8. "ctrl-c" to break into debugger
