Comment 2 for bug 393907

This is actually the proper behavior and your template file does not adhere to the format compliant with Debian templates. If you ran your template against Debconf::Template->load(), you'd get a similar message pertaining to missing fields. The fun part is that this is not detected when building a package but only when installing!

Anyways, aside from the fun of Debian packaging, Checkbox can be slightly more flexible. So, I've pushed a branch for review which extends the parser to allow for an arbitrary number of newlines between and at the end of the test definitions.
