If there is a newline?? There should be a newline at the end of each
line of the file; with luck the reader will not complain if the final
newline is missing.
Expected behaviour for various raw file contents:
1234 => one row, ok (with luck)
1234\n => one row, ok
1234\n\n => first row ok, 2nd is empty, expect error message
1234\n5678 => two rows, ok (with luck)
1234\n5678\n => two rows, ok

Simply: avoid having empty or blank lines in the .import file,
especially at the end, where they're not obvious.
IMHO that error message is carrying "Lite" a little too far; some prefix of:
data mismatch in line 2, column 1 (foo): expected integer, found ''
might save some wear and tear on the help desk :-)
