I can't reproduce this bug either in version 3.5.15. Copy/pasting normal java code works fine; the only problem I can envision is trying to paste in a GIANT amount of text. Putting in a megabyte's worth of text took a while but didn't crash, but trying to paste in 10M of data hung my system for a few minutes until iceweasel finally died. So I'm guessing you tried to put in way too much data into the browser and it just got overloaded. Here's what my log was:

Not sure if there's a fix other than perhaps a more graceful exit.
