This is probably due to us circumventing the normal KApplication shutdown.

this bug is also in kde 3.2.2

CVS commit by mattr: 

Save the settings and quit kopete when we're not using the tray, instead of
just hiding it. Fixes bugs 81143 and 81809.

Please reopen.

This bug exists in 0.10 (Suse rpm, kdenetwork3-3.4.0-18). Even normally
quitting the application (^Q or File->Quit) doesn't make the setting saved.
