To reproduce go to any page which has a combo box. Click any link, and before the next page load is committed, click the combo box. After the new page load is committed click an option, or otherwise make the popup go away: crash. This seems to be GTK+-specific, but I'm not yet sure. I'll try to reproduce in other ports. I'm still doing a debug build to get a proper backtrace, but this is what I got from a release build: Program received signal SIGSEGV, Segmentation fault.

Comment on attachment 30933 [details] Avoid crashing when popup is open during page transition Alternative solution to the client null checkproposed by zecke on IRC. Disregard the fact that the changelog still mentions nullity check, it is already fixed in my local copy, which I will commit if I get r+ =P
Comment on attachment 30933 [details] Avoid crashing when popup is open during page transition Makes sense.
