The above was running gui/gtk-gnash easyvideo.swf with Gnash 0.8.9dev
(master-19991-f07c4e9).

media.flv (loaded by easyvideo.swf) is a symlink to snow.mpg (the infamous
snow plugin demo). I could not reproduce the same problem on the 64bit
machine. This one is linux-lucid-x86 (the buildbot slave).
