When trying to play a video using mplayerplug-in on firefox, firefox segfaults. For example, when I try to play a video, mplayerplug-in buffers, and then begins to play. But after a while, firefox/mozilla crashes. Here's a sample gdb session: Starting program: /usr/lib/MozillaFirefox/firefox-bin (no debugging symbols found)...(no debugging symbols found)...(no debugging symbols found)...(no debugging symbols found)...(no debugging symbols found)...[Thread debugging using libthread_db enabled] [New Thread -1217173824 (LWP 26272)] [New Thread -1220047952 (LWP 26276)] [New Thread -1240667216 (LWP 26277)] [New Thread -1249092688 (LWP 26278)] [New Thread -1262126160 (LWP 26279)] [Thread -1262126160 (LWP 26279) exited] [New Thread -1262126160 (LWP 26280)] [New Thread -1276150864 (LWP 26281)] Detaching after fork from child process 26282.

I was trying to play a move clip from http://movies.yahoo.com Reproducible: Always Steps to Reproduce: 1.Run firefox/mozilla. 2.Play an embedded video clip.

This is an upstream bug that's fixed in mplayerplug-in-2.75. Unfortunately, that version isn't in portage, yet. See bug 74634.
mplayerplug-in-2.80 is in portage now, please reopen this bug if it's still a problem with the new version.
