This is odd, and I don't see this variable used in the lisp source.
>From the "Reporting Bugs" part of the manual:

----------------------------------------------------------------------
   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.

Please could you send us a *Backtrace* buffer if you get one.

Actually, you've just shown me a nicer way to search the archives than
I knew before -- at the bottom of the URL you sent me I see a green
"Search" box.

Thanks,
