Public bug reported:

Binary package hint: compiz

Occasionally my whole desktop hangs, only the mouse cursor moves. Compiz is running at 100% cpu usage in this loop (forever!):
   0x00007f3a515866d0 <+224>:   mov    (%rax),%rax
=> 0x00007f3a515866d3 <+227>:   cmp    %edx,0x10(%rax)
   0x00007f3a515866d6 <+230>:   jne    0x7f3a515866d0 <_ZN13InotifyScreen13processEventsEv+224>

0x00007f3a515866d3 in InotifyScreen::processEvents() () from
/usr/lib/compiz/libinotify.so

I'm running natty amd64 with gnome2 (ubuntu classic) shell.

After having a look at the source code of this specific plugin I suspect
that there is a bug in an iterator loop. I created a patch, but haven't
had time to test it so far. Maybe this helps.
