Maybe this bug is fixed in the devel version?
After building the debian version xserver-xorg-video-intel (2:2.2.99.903-1) I had no crash until now.

from Changelog:

    Always bind memory after agp aperture allocation

    This fixed the crash appearing for Xv buffer memory, which appears
    allocation and free happening in stolen memory. We should always
    try to bind for stolen memory for correct protect setup, otherwise
    we might get fault that stolen memory protect reverted to non-r/w
    after previous free and unbind.

    Credit goes to Lukas Hejtmanek to identify the real problem of Xv
    crash!
