Infopath Crashes on secondary retrieve data connection

[jb]

I have a very simple web service that I call takes in 1 string parameter and
returns xml. The asmx runs fine from the web using the simple data type
input and returning an xml document.

When adding a retrieve data connection infopath recognizes the webservice
and the functions but.. when i select the function and click next in the
wizard ... InfoPath immediately (no delay) crashes/closes with no error
message.

The form in question is complex. I considered this complexity might have
something to do with the issue so I created a new form and tried to add the
data connection. It crashed immediately in the same manner.

Is there another way to add a dataconnection to work around the general
InfoPath instability. Can this be added directly to the InfoPath
manifest.xsf?

This is now resolved. Changed my web service to return a string rather than
an xmldocument. Removed some file save functionality in case this was
causing a security exception.
