gst-launch segmentation fault with identical frames ( corrupt stack ?)

[pirpi srd]

I have usb logitech webcam. I want to stream video over network. I am using
the following pipeline for video streaming.

gst-launch-0.10 v4l2src !
video/x-raw-yuv,width=640,height=480,framerate=30/1 ! x264enc
speed-preset=ultrafast tune=zerolatency ! rtph264pay ! udpsink port=5000
host=192.168.0.101

But after streaming particular amount of time, I am getting segmentation
fault saying

Caught SIGSEGV accessing address 0xb5142000
#0 0xb6c6e276 in ?? ()
#1 0xb6cdf1e8 in ?? ()
#2 0xb6cdf1e8 in ?? ()
spinning. Please run 'gdb gst-launch 1322' to continue debugging, ctrl-c to
quit, or ctrl-\ to dump core.

Then I have tried to debug the gst-launch using gdb. I got following
information with the gdb

#0 0xb6c6e276 in ?? () from /usr/lib/arm-linux-gnueabihf/libv4lconvert.so.0
#1 0xb6cdf1e8 in ?? () from /usr/lib/arm-linux-gnueabihf/libv4lconvert.so.0
#2 0xb6cdf1e8 in ?? () from /usr/lib/arm-linux-gnueabihf/libv4lconvert.so.0

Backtrace stopped. previous frame identical to this frame( corrupt stack ?).

I have installed the libv4lconvert0 libv4l-0 libv4l-dev packages already.
still the same error is showing.

Please help me with this.

Thanks
