Description:
After some time when a video conversation (GTalk/XMPP) is active, the system would hang. The clock still ticks, but all input devices are unavailable (e.g. the mouse cursor does not move, the keyboard does not react). This issue is discussed[1] and a pull request is already sent for 3.6.

The upstream pull request is at http://patchwork.linuxtv.org/patch/13573/
After applying the patch manually, I did not have any lockup issues anymore, nor did I detect any regressions.

Additional info:
* 3.4.4-3 was affected, 3.5-rc7 was still affected and looking in the branches of 3.4 and 3.5, those are still affected.
* hardware: USB webcam (integrated in laptop screen), 04f2:b18d Chicony Electronics Co., Ltd

Steps to reproduce:
1. On affected systems, start Pidgin
2. Start a video conversation
3. Wait
