[Kdenlive-devel] a few backtraces

Sat Jul 24 07:09:46 UTC 2010

Hello,

Here are a few crashes I've seen yesterday and today. I don't know how to
to trigger them so maybe a bug report would be useless, so here are just the
backtraces which are pretty deeply in MLT. I have not seen them when
kdenlive is run from gdb yet.
