Description Marcin Lewandowski 2013-06-27 10:41:48 UTC 
Hi,

I encounter random crashes in gst_collect_pads_chain(). 

It happens in complex, dynamic pipeline when I remove one of the branches from adder. Associated adder pad is already released, ghost pad in branch's bin is still present. Branch is not stopped yet.

Can you provide a testcase to reproduce this?

Not really, it happens randomly on software that is not open source. I wasn't able to find any way to reproduce this.

Can you get a GStreamer debug log of a run that causes the crash?

Alright, let's close it then. If it's still a problem, someone will run into it again. Thanks for re-testing.
