Well, yes. But maybe you can get the benefit of both :)

I see. Would be a patch in this direction welcome? I.e. an optional call
to libpurple that would wither disable calling of purple_plugins_probe()
or prevent the default library path to be added to the search paths?

Mhm, this is really a hack, but could work for as a workarund (don't
worry, just temporarily :)

I agree. In fact I took the time to track down the problem and provide a
patch/fix for both.
