It could any number of things.

The trap is no terribly revealing. What driver does Theseus say owns the
1200 selector? Use System->General system->Device drivers to get a list.
Then scan the Strategy column for selector 1200. I suspect it will be the
NUL driver. That is confirm that my reference dump file has the same
general content. If so, the exception is in

# ln 1200:7d6

1200:00000700 OS2KRNL DevIOCall + d6

which says some driver is passing bad data to a helper rountine that lives
in the kernel.

I'd need to look at a trap dump file before I can say much more.
