Is this a Regression from Dec 13 checkins?

Reproducible: Always

Steps to Reproduce:
1. Open nightly build 
2. copy and paste some text into some form fields (eg. in bugzilla)
3. crash @ BuildTextRunsScanner::FlushFrames(int, int)

The build is actually Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2a1pre) Gecko/20081212 Minefield/3.2a1pre.  

The useragent id listed in comment 0 is because i had to open this bug on a noncrashy version.

Can you retest with a trunk build or tonight's nightly?

Same happens with the URL given on bug 444375 (http://profiler.noaa.gov/npn/npnWindViewer.jsp). Same on Windows but with a less informative stack:

0  	xul.dll  	gfxTextRun::`vector deleting destructor'  	
1 	xul.dll 	xul.dll@0x3051d6 	
2 		@0x0 	
3 		@0x80000009

Crashes with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2a1pre) Gecko/20081212 Minefield/3.2a1pre

Runs fine with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2a1pre) Gecko/20081213 Minefield/3.2a1pre

The backout of the patch on bug 430332 has been fixed this crash.
