Bug 29496 – [GTK] Sometimes crashes when a page is destroyed/loads another URL while playing video

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Gustavo Noronha (kov)]

I am using http://limi.net/articles/firefox-3.7-4.0-design-directions/ to test. I click the very bottom/left corner to start the video playback, then click reload. Rinse and repeat 'till I get a crash.

Zan told me on IRC this is probably the same thing that is causing media/video-seekable.html to crash.

This is a bit hacky, but a real fix requires a bigger rework of the code that I am unable to do right now. Since it's a crash, I'd rather plug it quickly, and refactor the media player later.

Reopening to remind us that this needs a "real fix".
