Running 11.04 on a netbook. Whenever I'm off AC power, some application wants to access my default keyring, but there is no indication of which application this is. Naturally, I refuse access (granting access to unknown applications would defeat the purpose of the keyring), and as far as I can tell, this does not affect any of my running programs.

So what I'm wondering is:

1. How can I find out which application wants access to the keyring?
and
2. Why does this only happen when I'm on battery power? (I suppose answering 1. might also answer this)
