Segmentation fault in socketNotifierSourceCheck(_GSource*) qeventdispatcher.cpp

[AditiH]

I'm facing crash issue in GPRS packet transmission and application crashes unexpectedly. After debugging I got corrupt stack.
Please anybody can suggest some solution to detect the issue properly.
Following is the stack trace:
