Autocomplete forms works very well here, but it crashes while using the option "Stop for exceptions" of Venkman.

Steps:
 1 - Open Venkman
 2 - Check "Debug --> Throw Trigger --> Stop for Exceptions"
 3 - Uncheck "Exclude Browser Files"
 4 - Type your name on the 'Name' field
 5 - Preview a empty comment here: http://weblogs.mozillazine.org/weirdal/archives/018562.html
 6 - Back
 7 - Start typing your name one the 'Name' field
 8 - Press the down key
 9 - Press tab
10 - Hit 'continue' on Venkman

It will crash...

nothing personal with Alex, but I got the crash in that page ;).

I had missed those assertions, but now it looks it's clearly a cycle collector related bug.

I doubt this is cycle collector related. The assertions from the cycle collector were fixed in bug 401687, but they wouldn't cause a crash. Things would just leak more.
