I could reproduce the problem when trying to downgrade to 1.7.3-6
because lpq freezes with the new version.
Here's the backtrace of the lpstat process:

"lpstat -h /var/run/cups/cups.sock -r" froze for some time, but it's
now OK.
I think that the problem is that during the upgrade, an attempt to
connect to the remote print server is done. There's no reason to do
this (the local configuration mustn't depend on remote data!).
For instance, once every package has been downloaded, it should be
possible to upgrade with the ethernet cable unplugged.
