libs: cannot check kernel uptodateness

My last servers installed with Debian wheezy or Ubuntu precise has started
to show a yellow alarm at libs with message:

*One of /proc/config.gz and /boot/config-3.2.0-4-amd64 was not found,
cannot check kernel uptodateness
• However

ls -l /boot/config-3.2.0-4-amd64
-rw-r--r-- 1 root root 129065 Jun  9 15:47 /boot/config-3.2.0-4-amd64

A search at Google shows me several xymon monitor with the same yellow
alarm active but I can found references about it.

Any comments will be appreciated.
