The limit on the Add Data Widget is surprisingly small. It doesn't tell you the limit either. It won't even take a 46KB .csv file. That almost makes it kind of useless. I'm here wondering if I can manipulate the widget to increase the limit? Or can you even customize out-of-the-box widgets?
EDIT: The actual error/warning reads:
The number of records in <file> exceeds the maximum threshold.
