Comment 9 for bug 551311

I found out that if you change the speed of a clip, apply the settings, and then try to go back into the properties it crashes. After using a lot of print statements I found the call that causes the problem:

In classes/video.py the last call to "self.c.start()" in the function load_xml crashes.
At the beginning of load_xml we have 'self.c = mlt.Consumer( self.profile, "avformat", export_path)'.

I'll investigate more tomorrow.
