Processing triggers .... ?

[Thilo Six]

after upgrading du gutsy i now got these messages everytime when doing
aptitude things:
<--------------------------------------------
Processing triggers for libc6 ...
ldconfig deferred processing now taking place
-------------------------------------------->

Anyone knows about that?

I have heard about triggers, but i wonder, if there is one task missing and
it´s complainig about?

(should i fill a bugreport?)

TIA
