VBoxHeadless crashed with SIGSEGV

[Sean Young]

The crash most likely occured while it was running one of the virtual machines in the BOINC project LHC@home, Test4Theory sub-project which uses virtual machines running in the headless VirtualBox client.

May be related to the many other SIGSEGVs reported for VirtualBox (will check the dump log and see if this is an obvious dup)
