[PySide] Program received signal SIGPIPE, Broken pipe.

[William Dias]

Hi..

I have a pyside application which captures frames from a webcam using
opencv and then sends the pictures to a webserver using a newly created
thread.
I ran an automatic test yesterday, and after 2 hours the program crashed
with a SIGPIPE error. The backtrace is shown bellow.
I using python 2.7.2, pyside 1.1.1 and opencv 2.3.1 on ubuntu 11.10.

Any lead of what's is causing the problem?

Thanks for the help.
