After a hard-reset of my machine, Firefox will not display windows anymore. It will open, I can see the menu bar and interact with it, but new window and new tab simply don't display new windows. 

Running it from the command line, whenever I attempt to open a new window or tab I get the following error: 

2010-10-09 14:40:46.391 firefox-bin[589:613] Mozilla has caught an Obj-C exception [NSImageCacheException: Cannot lock focus on image <NSImage 0x1a106410 Size={0, 0} Reps=(
)>, because it is size zero.]

Restarting the Firefox in safe mode, with add-ons disabled, gets me in; on a hunch, I disabled the Feedback extension (ver. 1.0.3) and restarted the application, and now all appears to be well. I've since re-enabled it, and all continues to be well.

I don't claim to understand what's happened here, except that now it works again.

Reproducible: Always

Steps to Reproduce:
1. Hard-stop Firefox in just the right way at just the right time.
2. Restart Firefox
3. See nothing
Actual Results:  
No window, limited functionality.

Expected Results:  
The interwebs.

I'm not sure how to rank this - it seems like the most rare of corner cases, but it also cripples the product. Marking it "normal" and deferring to whoever triages it.
Version: unspecified → 4.0 Branch
