[gst-devel] gst_object_unref on a bin

[David P. <da...@ne...>]

Hi list,

Is anyone having trouble calling gst_object_unref() on a bin? When I try
either directly or on a pipeline that contains the bin, a segfault occurs
(in the case of the higher-level pipeline, it seems to be unref'ing things
properly until it recurses down to the bin). Here is the relevant part of
the gdb backtrace:

#0  0x400af7be in g_type_check_instance_cast () from
#/usr/lib/libgobject-2.0.so.0 1  0x40047752 in gst_bin_dispose
