Pipeline exits without error

[Petteri Matilainen]

I have a functioning pipeline, but after about 2 days gstreamer just 
exits without any error. Like this:

How can I debug this further? I'm using version 1.6.1 compiled from 
source. The full pipeline is:

$gstlaunch -v -e uvch264src initial-bitrate=$init_bitrate 
average-bitrate=$avg_bitrate peak-bitrate=$pk_bitrate 
rate-control=$rate_ctrl iframe-period=$if_period name=src auto-start=true \
  src.vfsrc ! queue ! 
video/x-raw,format=\(string\)YUY2,width=320,height=240,framerate=10/1 ! 
fakesink \
  src.vidsrc ! queue ! 
video/x-h264,width=$vid_width,height=$vid_height,framerate=$vid_framerate,profile=$vid_profile,stream-format=$vid_frmt
