Hitting "Stop" in venkman hangs the browser; closing the debugger window crashes the browser

Reproducible: Always

Steps to Reproduce:
1. Start Seamonkey -- there is only one (empty) window
2. Start venkman (Tools - Web Dev - Javascript Debugger)
3. Hit the Stop button (red cross)
=> at this point, the debugger isn't painted anymore, all panes turn black, and the whole browser hangs (becomes unresponsive)
4. Close the debugger window
=> this crashes the browser

I tried 3 more times. It crashed twice.

The third time, the debugger actually managed to stop (it took 2-3 seconds) and closing the window only produced a warning along the lines of "are you sure you want to quit while you are debugging?"

From the previous stack traces, here are the 3 different places where the crash occured. The first shows up in bug 583496

[@ nsTreeBodyFrame::PaintColumn(nsTreeColumn*, nsRect const&, nsPresContext*, nsIRenderingContext&, nsRect const&) ]

[@ nsTreeBodyFrame::PrefillPropertyArray(int, nsTreeColumn*) ]

[@ RuleProcessorData::RuleProcessorData(nsPresContext*, nsIContent*, nsRuleWalker*, nsCompatibility*) ]

I don't think this is a dupe, as this bug covers multiple crash signatures, only one of which is covered by bug 616899.

But it may not matter, I hear the JS debugger is deprecated?

[Wayne Mery (:wsmwk)]

correct, it is deprecated
