Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Curtis (bcurtiswx)]

Checked for private information in attachments. Found none. Marking public.

[Sebastien Bacher (seb128)]

Thank you for your bug report.

Till, could you have a look to this one? That's the cups error the most reported on errors.ubuntu.com for 13.10

Not sure whether it is CUPS or Avahi, therefore added Avahi.

[Till Kamppeter (till-kamppeter)]

For me this looks rather like an Avahi problem than like a CUPS problem. The assert failure happens when the last element of a list of timeouts is removed but the pointer to the list is not pointing to this element (and so not to the list, or the element is not member of the list). This timeout list (elements of type AvahiTimeout) is managed internally by Avahi, CUPS does not access them directly.

[Till Kamppeter (till-kamppeter)]

I asked Mike Sweet, the author of CUPS, what is happening here and he answered:

----------
Based on the bug report, it sounds like this is an internal bug of Avahi.

The fact that a production build of a library is forcing an assert is troubling - it doesn't allow the caller to perform any recovery and IMHO makes Avahi totally unsuited to production use at all.

The fix on the CUPS side is easy - bundle mDNSResponder (Apache license) with Ubuntu and build CUPS against it. For Avahi, we'll need to get someone from Avahi to look at the issue...
----------

Seems really to be an Avahi bug ...

Please boot a Saucy (13.10) or Trusty (14.04, under development) live CD/USB stick and check whether cupsd is stable there. Please post your results here.

[Bruce Pieterse (octoquad)]

Both Ubuntu 13.10 and 14.04 (Beta 2) were tested.

13.10
--------
Printer 1: HP Color LaserJet CM2320nf MFP
- No crash logs were generated when adding this printer.
- Test page printed without any errors
Printer 2: HP Laserjet Professional P1102
- No crash logs were generated when adding this printer.
- Test page printed without any errors
- Automatic detection and installation of device occurred with cupsd (noticed a service restart)

14.04
--------
Same as above.

If you need anything else, please let me know.

[Robin (robingape)]

This bug occurs on a fully updated Ubuntu 13.10 installation, incidentally with an HP printer directly attached.

[David Fraser (davidf)]

I also had this on a fully update Ubuntu 13.10 installation, with a Canon iP2000 printer attached
