Package: dpkg Version: 1.14.16.6 Severity: normal I downgraded glade from sid -> etch to get code generation functionality back, and then upgraded it from etch -> sid, which failed because dpkg was doing rm on an empty directory instead of rmdir. Initially I thought this was a bug in glade for not supporting upgrades from etch, but it turns out to be due to a bug in dpkg where downgrading from glade 3.4.1-1 in sid to glade 2.12.1-7 in etch does not convert the glade doc directory from a directory to a symlink as it should:
