Konqueror crashed while showing an HTML i'm editing and the cursor rolled over a piece of displayed text in a span tag (line 64 of the html file) containing bad coding.

The bad file is online, unlinked from anywhere, for your testing:
http://celestialvibrations.com/index-crashes-konqueror.html

The bad coding in the html file is line 64:
 <span  onMouseOver="detailedwords("test me")">

I would expect nonfunctional mouseover actioin, perhaps gibberish displayed, maybe an error message or anything ugly yet benign - not a crash.  Firefox handles the page fine (though rollover is nonfunctional).
