That sounds like a bug in libpurple, which should have a cache for the
plugins (to know what each one of them does), or use other types of
files for that purpose (like most GNOME apps do with ad-hoc desktop-like
files).

That seems excessive, especially given that all those 3 "applets" mainly
use components such as GTK+ and D-Bus, which would be loaded by other
parts of the system already, and thus shared.

That's probably due to the amount of memory used by the pixmap backdrop
(ie. it depends on your resolution and number of screens). I believe
there's already discussions of that on Bugzilla.

And I wouldn't recommend running without the 3 applets you mentioned if
you want to get a network connection, have Bluetooth working or want to
suspend your laptop.
