Bug: Plugin.pm evals plugins w/o checking for errors

Plugin.pm uses eval to load plugins. It doesn't, however, check the error return ($@), which can cause silent and hard to track down problems.

For example, we had a misconfigured mod_perl which was attempting to load a shareable File::Glob (even though it was statically linked into Perl) when MathModePlugin was eval'd. MathModePlugin was compiled (and thus loaded into mod_perl) but the module's initialization code (the part not in subroutines) was never run, causing bizarre behavior when the plugin was used. The only hint of why this was happening was in the error thrown by Perl via $@.

This should have been fixed in the TWikiRelease01Feb2003. This needs to be verified, possibly it got "unfixed" by mistake.
