I dont crash in this site. Is something that i have to do to provoke it ?
Comment 4 Marcin Ślusarz 2011-09-01 20:33:00 UTC 
Heh, it stopped crashing. But it did crash several times in a row. Maybe some ad triggered it.

Can we close this report bug report then ?
Comment 6 Dimitrios Glentadakis 2011-12-31 07:34:47 UTC
