Comment 24 for bug 956071

Look around the internet, I may have found what appears to be upstream reports:

Debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=681796

Xorg:
http://patchwork.freedesktop.org/patch/11531/

Debian is showing this SIGSEV:
XIChangeDeviceProperty (dev=dev@entry=0x7f4bac237fa0, property=<optimized out>, type=type@entry=19, format=format@entry=8, mode=<optimized out>, mode@entry=0, len=len@entry=1,
    value=value@entry=0x7fff092e860f, sendevent=sendevent@entry=1) at ../../Xi/xiproperty.c:772

And Xorg claims:
is reporting a memory leak:

Error: Memory leak (CWE 401)
   Memory leak of pointer 'prop' allocated with XICreateDeviceProperty(property)
        at line 774 of Xi/xiproperty.c in function 'XIChangeDeviceProperty'.
          'prop' allocated at line 700 with XICreateDeviceProperty(property).
          prop leaks when handler != NULL at line 768
              and handler->SetProperty != NULL at line 769
              and checkonly != 0 at line 772
              and rc != 0 at line 772.

I'll forward this info to Debian and see what they say.
