Marco's patch of 2003-05-04 re-enabling mozilla notifiers causes an
inifinite loop to occur if you have the GConf key
/system/proxy/autoconfig_url exists.

I'm not too clear why - but at some point coming back out of setting up of
this pref another call is made to mozilla_notifiers_init().

The patch attached will show some top-level debug info that let's you see
what's going on.

As a temporary fix affected users can use gconf-editor to unset
/system/proxy/autoconfig_url and startup will proceed as normal. 

To reproduce the bug set this pref (Note: It doesn't have to have any
specific value - just has to exist!)
