I didn't really knew in which category i should put this bug, but here it is:
When i try to render a project with Pitivi, the process blocks on cuts in the timeline. By cuts i mean : 2 video clips put side by side.
It's weird because it does it only with some videos (meaning i could render videos with cuts in them with no major problems.

It does it using the following video encapsulators:
- oggmux
- avimux
- mpegtsmux and mpegpsmux

All the settings used for video and audio are default.
I precise that the video that were in the timeline where in fvl format, with an ogg audiotrack.
When i render in fvl, it does render until the transition, then keeps going, blocks at then end (stays at "one sec remaining) and if you read the file created, it actually only rendered until the cut.
