Mono's XSP crashes on browser connection

Hi, I have a port for Mono's XSP web server for ASP.NET but it has never
worked from 1.0 to the latest version, 1.0.6. The crash has always been
the same. Finally I've had a chance to sit down with a machine and
generate a usable backtrace. The attached backtrace was generated on
-STABLE from February 19 using Mono 1.1.4 after connecting to the server
with a browser. (Mono 1.1.4 does not build on -CURRENT right now which
has become the version I'm focusing on for crashes since 1.2 will be out
in late April. The crash does occur on Mono 1.0.6 as well which is in
ports and does build on -CURRENT.) If needed, I can regenerate the
backtrace using -CURRENT once 1.1.4 builds. The xsp and mono-devel
ports can be found here:

Thanks,
Tom
