Description cyberic99+gnome 2013-01-02 23:55:10 UTC 
pitivi version a6a2981d1d685f4b1517ff957a6b57b2c3b00082 compiled on archlinux 64bit.
I import a video, drag it to the timeline and... pitivi is frozen.

The console displays:
ERROR 00:42:52 pipeline             _busMessageCb: error from <__main__.GstVideoTestSrc object at 0x18adaf0 (GstVideoTestSrc at 0x2940830)>: Internal data flow error.

I have a video to show what I'm doing:

The same happens with the 3 video files I tried...
Comment 1 Jean-François Fortin Tam 2013-01-03 01:24:45 UTC 
Ah yes, that's a known bug caused by the last two commits by Sebastian in gnonlin (da3a5a5b2af498a2b and d196cd3cdc850f). Reverting to the commit before those (1230a8df37a4) makes it work a tiny bit better.

Nothing that can be done on the pitivi side, so reassigning.

As far as I know, this has been fixed in gnonlin now:
