gdb backtrace log

Thx Gurkirpal for the report. The other day I was going further into https://bugzilla.gnome.org/show_bug.cgi?id=779642 and I wonder if it is not the same issue in the end, see its commet #6. Created attachment 130320 [details]
backtrace
changed backtrace log to the right one.
Thx Gurkirpal, this time the backtrace looks different than the gst bug I pointed above.
I get the same result with AMD, dri/radeonsi_drv_video.so . Note it crashes with RGBx and BGRx but not with RGBA and BGRA.

I can read buf size 0 but it would require further investigations.
