I had problems like this switching between home and work when there was inconsistant fieldname case between the two databases. It would especially get me on the dictonary.xml file when calling validate(). Not sure if this is your issue as you are only doing a genericlist. you might try renaming or deleting your dictonary and metadata files, then if that works you can merge in any customization you may have bit by bit until you see the problem.(either mismatched case or unescaped symbols)

grasping at more straws....

Ray,

I can't help with the error, but have you updated Reactor with the
latest from the repository?  I believe some bugs have been fixed
since the build that shipped with MG.  Just grabbing at straws here.

Good Luck,
Brad
