eventspace internal error when copying drracket internal error dialog

I provoked this by:

1. Starting with some out of date zos
2. Running something in DrRacket that triggered an internal error due to the out of date zos
3. Try to copy the error text from the DrRacket internal error dialog.

Here's the racket/gui error:

internal error: wrong eventspace for constrained event handling

/home/samth/sw/plt/extra-pkgs/gui-lib/gui-lib/mred/private/wx/common/freeze.rkt:9:0 internal-error
/home/samth/sw/plt/extra-pkgs/gui-lib/gui-lib/mred/private/wx/common/freeze.rkt:36:0 constrained-reply6

And here's the previous DrRacket error:

Reproduce the failure by copying text from the DrRacket internal error dialog after the out-of-date compiled-code error. Start with gui-lib/mred/private/wx/common/freeze.rkt, then trace the DrRacket path in drracket/private/syncheck/blueboxes-gui.rkt and the related coroutine and timer files named in the stack trace. Done means copying the error text no longer triggers the wrong-eventspace error.
