[gst-devel] Fun crash in opt

[iain]

I know I should bugzilla this, but ...

Pipeline is {filesrc ! typefind ! spider ! custom-sink}
The pipeline of {filesrc ! mad ! custom-sink} works fine.
When I call g_object_unref on the thread I get this crash

Program received signal SIGSEGV, Segmentation fault.

marlin-pipeline.c:83 is the g_object_unref call.
Any ideas for debuggin it further?
