A double fault on 32-bit x86 is usually indicative of a blown stack.
This could be a bug due to infinite recursion, or simply a very deep
stack.  Sherry Moore has increased the default stack size on 32-bit from
2 to 3 pages in build 105, and that will hopefully alleviate instances
of the latter.  See:

6766854 BAD TRAP: type=8 (#df Double fault) (Xeon)

For some immediate relief (assuming that you're not running into some
infinite recursion bug somewhere), you can increase your stack size by
placing the following in /etc/system (a reboot is required for this to
take effect):

set _defaultstksz=0x5000
