It would help if those bug reports included DEBCONF_DEBUG=. protocol dumps so we could see why blank lines were being sent to debconf. It seems likely that the packages are doing something wrong to screw up the protocol like this. The protocol has no provision for either blank lines or comments; the reason for the code above is unclear (it was introduced when the thing was first written in 1999). Debconf seems to do the right thing protocol-wise by responding with an error to both -- I've gotten rid of the uninitialized value warning. -- see shy jo
