Description Adam Williamson 2014-01-08 20:28:07 UTC

There's a 25 second delay on launching gedit in Rawhide currently, for me. If I watch journalctl, I see this:

(immediately on running 'gedit' as a regular user)

Jan 08 12:13:35 adam.happyassassin.net dbus-daemon[912]: dbus[912]: [system] Activating via systemd: service name='o

Jan 08 12:13:35 adam.happyassassin.net systemd[1]: Unit avahi-daemon.service entered failed state.

(25 seconds later)

Jan 08 12:14:00 adam.happyassassin.net gnome-session[2279]: Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.

and then gedit starts up. Note, I do have gedit set to run during session start, which could possibly be related somehow. Not sure if the bug here is in gedit, avahi or something else.

Comment 1 Adam Williamson 2014-01-08 20:28:39 UTC

'ps aux | grep avahi' returns nothing. Perhaps the problem here is that the avahi stuff has moved into systemd, or something?

Comment 2 Adam Williamson 2014-01-08 20:42:54 UTC

hum, looks like I had some stale files in /var/run/avahi-daemon, cleaning those out seems to have fixed it. Re-assigning to Avahi - I think if /var/run/avahi-daemon/pid is empty it shouldn't claim to be running as PID 0, but catch that something weird has happened and deal with it somehow.

Comment 3 Jaroslav Reznik 2015-03-03 15:22:46 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

Comment 4 Fedora End Of Life 2016-07-19 20:04:37 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
