New Revision: 2947
URL: http://svn.gnome.org/viewvc/gnome-power-manager?rev=2947&view=rev

Log:
2008-09-09  Richard Hughes  <richard hughsie com>

* src/gpm-cell-array.c: (gpm_cell_array_emit_system_action),
(gpm_cell_array_percent_changed):
* src/gpm-warnings.c: (gpm_warnings_time_is_accurate),
(gpm_warnings_get_state), (gpm_warnings_init):
* src/gpm-warnings.h:
Only use the time for policy decisions when it is accurate, and GConf
is not disabled.
The bug is that critical battery actions are blocked while GPM doesn't
have a good profile for the battery.
This means that the first time you try on a new system, it fails.
Based on a patch from Joakim Andersson, many thanks.
