Bug#652013: gdm3: simple greeter sends bad timestamps in _NET_ACTIVE_WINDOW and no_focus_window (?)

[Daniel Kahn Gillmor]

Package: gdm3
Version: 3.0.4-4
Severity: normal


The following lines appear in /var/log/gdm/:0-greeter.log:

------------------------
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.

Window manager warning: CurrentTime used to choose focus window; focus window may not be correct.
Window manager warning: Got a request to focus the no_focus_window with a timestamp of 0.  This shouldn't happen!
------------------------


It sounds to me like gdm's greeter is doing something fishy or
considered dubious.

This pair of lines in particular shows up once or twice for every
state-change of the user-chooser, from what i can tell:

------------------------
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400007 (Login Wind)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
------------------------

the last two lines appear to only happen after an authenticated login,
but i'm not sure where they're happening.

I couldn't find anything in the gdm3 source that sends a
_NET_ACTIVE_WINDOW message directly, though, so perhaps the fault lies
deeper within some library; feel free to re-assign this bug in that
case.

Thanks for maintaining GNOME in Debian!
