I think I might have reproduced this problem! At least I get a similar Aborted
message. Here is a valgrind log (or part of one) that might be interesting:

What I did was to create a script that does play/stop (play=create pipeline and
set to state PLAYING, stop pipeline=NULL) over and over. I takes "a while"
(completly random) before I get this so this does not happen every time I play
something.

After looking at the code my thinking is that it might have something to do
with playlists that have an empty line at the end of the file but I am not
sure.

Oh, I am using the git HEAD (did git pull this morning) version of
gst-plugins-bad
