Segfault on starting a stream

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1.  Install sopcast-player and apply fix mentioned here:  
https://bugs.launchpad.net/sopcast-player/+bug/875793  (comment 2, to prevent 
segfault on start)
2.  Run sopcast-player and play a stream.
3.

What is the expected output? What do you see instead?

stream should start, but sopcast closes, strace output pasted below.

What version of the product are you using? On what operating system?

v 0.7.4, Ubuntu 11.10 x64.

Please provide any additional information below.

Crash is intermittent, seems to happen around the time that the video player 
should open and start showing the stream.  Doesn't make a difference using 
external player, as far as I can tell.

Strace output:

I am unable to reproduce the same problem, is this issue still affecting you?
