.... and nothing else seemed to happen, system did not go to sleep after pressing sleep button once.

This is the first time I see this bug.
Sleep button/xfce-power-manager used to work flawlessly before.

I will try to reproduce this bug, after filing this report 
(and running backups...) since this is my only computer.

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.x / Wheezy with a severity
less than important.

We don't have the ressources to reproduce the complete backlog of all older kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by sending
a mail to control@bugs.debian.org with the following three commands included in the
mail:

reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks

Cheers,
        Moritz
