After visiting a certain page written in मराठी, on attempting to search for a string, it appears that the rendered page FF has turned black.

On scrolling up, it seems that only a partial portion of the page has turned black.

I haven't run into any other side effects. FF appears to function normally otherwise. I can open tabs, visit other sites, etc.

Reproducible: Always

Steps to Reproduce:
Here is how I reproduce it consistently :


0> Disable all extentions & plugins

1> Start FF

2> Navigate to http://www.khapre.org/blog/marathi/labels/4KSu4KWAIOCkruCksOCkvuCkoOClgA==.aspx

3> Hit Ctrl-F 

4> Type the string "bi" without quotes.

5> Observe rendering bug


--------

In case the website changes in the future, I have saved an offline version.

Actual Results:  
A large portion of the rendered page turns black.

Expected Results:  
The rendered page should have remained as-is and the scrollbar should have been positioned at the point of the first occurrence of the string.

This might be relevant.

FWIW, I cannot reproduce this in latest Chrome, IE8 and Opera.

FF didn't crash, so the dump probably isnt of any use, but JIC.

I can indeed reproduce a black part of the page, but not anymore with Firefox 3.6 and trunk.
In two cases however (bigger, biggest) I miss the green highlight. 
This part of the page can't be selected at all.
IE8, Opera and Google Chrome mark the found text. Only with Opera I can also select the text.
So only the black is gone but there are still two problems (found text not marked and impossibility to select).
