Description Tim-Philipp Müller 2010-07-16 17:10:45 UTC 
+++ This bug was initially created as a clone of Bug #624504 +++

It should not be used since it runs the main loop from non main thread.

Here is the relevant part of backtrace:

Just for the record, this was fixed in -bad 0.10.19:

    camerabin: don't use gst_bus_poll() when creating preview image
    
    Avoid using gst_bus_poll() as the docs recommend. Use
    gst_bus_timed_pop_filtered() instead.
