If you use Accerciser to query the value of the progress bar in the downloads dialog, Firefox crashes 100% of the time.

Reproducible: Always

Steps to Reproduce:
1. Launch Accerciser
2. Start a download (I chose the latest nightly build of Firefox)
3. In Accerciser, browse in the hierarchy to locate the progress bar.  With it selected:
4. Choose the API Browser tab.  Near the bottom of the pane, locate the combo box that (likely) says "Accessible" and choose value.
Actual Results:  
Firefox crashes.

Expected Results:  
Firefox wouldn't crash. :-)

That patch is necessary but doesn't fix this bug unfortunately.

In fact when I crash it makes the whole desktop hang for me.

Joanie, does your desktop hang with this crash?
No desktop hang here, but I'm on the newest accerciser 0.1.2 from trunk. Hang could be an accerciser bug.
Sorry, should have added that I do see the crash. Just not the hang. :)
Latest Accerciser here as well and I too get the crash but not the hang.  But I don't think it's Accerciser:  Will mentioned that accessing the progress bar via Orca crashed Firefox as well.
