It appears that the "Incorrect permissions on /dev/pmu" dialog box pops up
before the bonobo/idl/whatever(??) stuff is properly initialised for the
settings-daemon which causes it to throw a trap.

This is pretty serious - it prevents gnome from starting *at all* on my
iBook. (settings-daemon segfaulting during session startup is bad)

The bug goes away if I create /dev/pmu and give my user account access to
it.  (it seems clear from the backtrace that the very act of displaying the
error message is what is causing the problem)

I'd rather gnome didn't try to touch /dev/pmu at all (as I have pbbuttonsd
running to take care of this).  I've simply hacked it out of my version but
that's not really a suitable solution for everyone....

NB:  problem also doesn't happen when gnome-settings-daemon is invoked
manually with no options.  gnome-session invokes it like this:

/usr/libexec/gnome-settings-daemon
--oaf-activate-iid=OAFIID:GNOME_SettingsDaemon --oaf-ior-fd=22

The --oaf-activate-iid is the problem switch.  The crash happens while
invoking manually if you give this switch.

No idea how any of this oaf/idl stuff works... just reporting what I
am experiencing.

This is a dup.
