[Mono-dev] Something bad happened between 2.6.1 and 2.6.3?

Dear List,

Been using Mono through Mod-mono and stand-alone programs for years with 
great success, great product.

Had an issue with 2.6.1 where a file handler in VB.NET was returning 
null, so upgraded to 2.6.3, and now nothing through Mod-Mono is working, 
and getting things like this in Apache error.log.

Please, am I doing something wrong??

Regards,

Ben.
