Error getting thrown. See attached image. http://code.google.com/p/groundwire-salesforce-campaign-combiner/issues/detail?id=1

Reported as an occasional error with no predictable steps to repro.

Waiting on info from the reporter on repro guesses.

No packages out of the ordinary really. It seems to only be happening when we are trying to combine multiple campaigns into one campaign. I think it may have to do with individuals that are members of multiple originating campaigns; but there hasn't been a clear pattern. Typically, if I try it a second time it will work.
