I see the crash without valgrind, but it doesn't seem to crash (or show valgrind warnings) when running under valgrind (and with the frame arena disabled).
Is there any way to prevent this bug, while it is resolved? Or is it too early? Thank you all.
We don't know yet. But please leave the testcase up (and unmodified) until we figure it out.
Ok. Don't worry about that
Just today I'm having problems with my connection. I uploaded a mirror here: http://www.daveruiz.net/firefox-crash/ Sorry about inconvenience
We did some tests and we managed to prevent crash Firefox. In the css file ui-styles.css, line 384, we have removed "vertical-align:-.1em" and apparently the page is no longer causing problems. I hope that helps you find the cause.
