dpkg/status corruption question

[Simon Bell <simon@calmblue.net>]

Hi Everyone,

My /var/lib/dpkg/status file became corrupt recently, I was getting this when 
trying to apt-update:

dpkg: error: parsing file '/var/lib/dpkg/status' near line 27803 package 'gcr':
 field name `°[?@' must be followed by colon
E: Sub-process /usr/bin/dpkg returned an error code (2)

I managed to correct the issue by pulling some stuff from /var/lib/dpkg/status-
old...

But, can anyone explain why the corruption (shown below) ended up containing 
the name of an old wireless SSID I used to use!?

The SSID was called 'airdrawndagger', it hasn't been active for over a year 
and the machine in question was clean installed after the Wireless network was 
replaced with another!

Is corruption of the /var/lib/dpkg/status file normal - I've never had it 
happen before now?

And does anyone have any idea how 'airdrawndagger' could have appeared there?!

Thanks : )
