Glib::filename_to_unicode bug?

[Dave Hayes <dave jetcafe org>]

Consider this code snippet:

  $filename = GLib::filename_to_unicode($_);

When running this against a large set of files, I get this error:

  Invalid byte sequence in conversion input 

Obviously this is a bug, how do I work around it?

Nearly all can stand adversity, but if you want to test
someone's character, give them power.
