This bug has been open because your package reported in the log that dodoc was called for non-existent, files. This is generally a lower-level mistake, but it's annoying as it fills with false positives the log of packages that might forget to die on doins failures. Please do correct this. Thanks.

Turns out I already had a version converted to ruby-ng that was ready to be committed but somehow left lying around for two years. :-( Now fixed with raggle-0.4.4-r2.
