Has anyone else seen a "500 Internal Server Error" when using the API
with Perl SOAP?  I am having no problems with most of the commands I
have tried, but when I try to modify a Campaign geoTargeting, I get 500
Internal Server Error with no other explaination.  I appreciate any
help.  Here is the request and response (with login credentials
removed):
