I reproduced the crash again today, this time with dbus debug symbols installed. The stack trace is attached. The stack is entirely avahi + dbus code, and the signature is very similar to other crashes reported in other applications. Looks like there might be a locking problem in the way cups uses avahi?
This thread describes a similar stack trace, and has some tips about using avahi in a threaded environment: http://marc.info/?l=freedesktop-avahi&m=122021745832173 Comment #12 of bug 524566 shows a very similar stack (without avahi), and the remainder of the bug has additional analysis. Bug 1055060 has a crash at the same location within dbus, though the bottom of the stack is much different. ** Attachment added: "stack trace w/ dbus debug symbols" https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1086019/+attachment/3453990/+files/Stacktrace -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1086019 Title: cupsd crashes regularly (daily) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1086019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
