Comment 19 for bug 1001516

Hmm, I've upgraded and downgraded Pitivi both, and none of them (oneiric, precise, precise-updates, quantal) are solving my rendering problem. Looks like the issue is elsewhere, perhaps in a library?

Here's some other interesting python tracebacks, having let it run for a long time "Estimating". Note the recursion error message...
