[Till Kamppeter (till-kamppeter)]

Seb, did you find any evidence why this is a glib bug? What leads to your assumption that it is not in cups-browsed?

[Sebastien Bacher (seb128)]

@Till, I don't think it's a glib bug, I see it as invalid because the backtrace is useless

[Till Kamppeter (till-kamppeter)]

To everyone who observed this crash: Are you able to reproduce the crash? If so, can you try to downgrade cups-browsed and/or libglib2.0-0 to older versions and see with which versions the crash goes away?

[Barry Drake (b-drake)]

Cannot reproduce crash - and crash has never occurred since that one instance.

[Launchpad Janitor (janitor)]

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

[wgroiss (wolfgang-groiss-gmx)]

For me today it seems also the first the bug occured: immediately after system boot (15.04) and login. No action was possible after typing the password. After long time of working the hard disc (no mouse pointer was seen), automatic bug report started. Reproducing was not possible. If it is later, i give a new comment.

@Alberto, why do you think it's an issue in avahi? could you give some details?
