Seminar: \end{slide} doesn't end \overlay's scope and gives postscript error
Dear seminar developers,
The following small document, when processed with LaTeX and dvips, gives
postscript file which has errors:
************************************
Error: /undefined in BOL
Operand stack:

Execution stack:

Current allocation mode is local
GNU Ghostscript 7.07: Unrecoverable error, exit code 1
************************************
The error occurs on the _third_ page, i.e. outside the slide
environment. It seems that \end{slide} doesn't properly close \overlay's
scope, since after removing the commented additional braces, the error
goes away.
It might not be an error in fact, but it should at least be documented,
I think. I have tested it with the files included in the latest
teTeX-beta.
When answering, please be so kind and keep the bug number in the Cc, so
that the mails get properly archived.
Thank you in advance, Frank

What is Crashing?

Crashing is \textit{not} the same as collisions. Here are some
examples why this is the case:
