Description Stanislav Brabec 2004-01-05 10:20:03 UTC

I have verified this problem on GNOME 2.4.1 with GAIM 0.74 and Gnome
gnomeicu 0.98.126 on SuSE Linux 9.0+supplementary GNOME and on Gentoo unstable.

Running both notification area applet and GAIM or gnomeicu, CPU
load of both of these raises nearly to 100%
(notification area applet about 60%, application 40%).

It seems that occur only in case, when program (gaim, gnomeicu) is started
before notification area applet is launched.

Closing either notification area applet or GAIM, CPU
load disappears.

I don't know, whether it is a bug of both gnomeicu and gaim or bug of
notification area.

How to simply repeat:

gaim ; killall gnome-panel
Related bug:
http://sourceforge.net/tracker/?group_id=235&atid=100235&func=detail&aid=867603

remove notification area applet, then gnomeicu and add notification area
applet (gnomeicu has related bug 125773, which prevents upper mentioned way
to repeat).

Comment 1 Stanislav Brabec 2004-01-05 14:15:15 UTC

GAIM with KDE notification area has not this problem. It is most
probably GNOME Notification Area issue, not GAIM.

I have tried to catch them in running state (sorry for
no debugging symbols):

Apparently fixed in gtk+ HEAD.
