Someone on askubuntu.com recommended I start the preference file with a CR (start preference description on the 2nd line in the file), include a trailing CR (empty line at end of file) and be very particular to not include any extra space characters after any of the attributes. This appears to have worked.
I have not seen this documented anywhere, or what it relates to, but it might be something that could be clarified with an update in documentation.
