Sure, I've uploaded the config to

It only happens when changing the cpu_share for another user and this
user needs to have a cpu hogging process running (like boinc, a
while-1 loop or similar).
It does not dump anything to the console, but the VirtualBox process
on the host takes all CPU - there seems to be no crash, but an endless
loop only.

I have reported it at
already, with a testcase (outlined above).
