[Pkg-utopia-maintainers] Bug#969531: avahi-daemon: retrieving printer info blocks printing until shutdown

[Michael Hatzold]

Package: avahi-daemon
Version: 0.8-3
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

OKI printer B432, conected via USB, no network cable attached.

   * What led up to the situation?
Want to print

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
select document, start print dialog, select my printer (config was done via
CUPS);

Now the printer appears a second time in the list with a different entry. If I
select this new entry, I am asked for CUPS PW twice, then it (a deamon,
whatever) starts retriving printer info which *never* completes.


   * What was the outcome of this action?
Either way, selecting my own entry or the new one made by the daemon, the
printer does nothing (I waited up to 45 minutes... until I shutdown my system.
Them during shutdown, there is a pause during which the document gets printed.

   * What outcome did you expect instead?
I want the printer to print after I sent the job.


*** End of the template - remove these template lines ***

There is a workaround:

In the original /etc/avahi/avahi-daemon.conf file, there is an entry "#allow-
interfaces=eth0".
Changing and uncommenting it to "allow-interfaces=eth9" solves the problem
(printer not conected via ethXYZ, though). Therefor I assume this hides a bug
or an improper default configuration.
