Same issue for me. There seems to be issue with capsfilter initialization and that happens after some ioctls failed from omap3camd side. Here is what I get in the strace log:
4823 13:38:16 write(2, "Camera pipeline error: \"Internal GStreamer error: negotiation problem. Please file a bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.\" , \"camerabingeneral.c(61): gst_camerabin_add_element (): /GstCameraBin:QCameraCameraBin:\nlinking capsfilter3 failed\" , 7 \n", 276) = 276
