Runtime error after choosing file

On the develop branch, after selecting a csv file and clicking the 'Next' button, I received the following runtime error:

There was an error.

I asked @zerocrates to look at the issue, and adding $this->fileObject->rewind(); at line 22 of src/CsvFile.php seemed to fix it, though he mentioned he's not sure why the problem was happening in the first place.

I do love a good mystery!
