Application dies when playing sound sometimes.

[weikun]

hi, all
     I'm a beginner on gstreamer, come from China. I need your help.
I add some gstreamer code to play sound in RedOffice(locale version of Openoffice.org in China) using gstreamer, but, at some times the RedOffice Application has not any response for input when it finishs the sound playing, the RedOffice must be killed and restart it.This computer is MIPS, linux debian 2.6.27.1, has install gstreamer0.10-plugins-base, and gstreamer0.10-plugins-good.

But the bug doesn't exist on another MIPS computer(MIPS, linux debian 2.6.18.1, has also install gstreamer0.10-plugins-base, and gstreamer0.10-plugins-good).It can play sound perfectly. Both machines use the same source code!

Also, the bug doesn't exist on ubuntu x86 machine.

Is GStreamer specific difference on MIPS ? Could anybody help me? It puzzles me a long time.
