Yes, a genuine bug :(

The problem is related with the fact that everything is a real counter, 
except the dstat_time output, which is just a string.

The only other plugin that outputs a string is the app plugin and it 
suffers from the same problem.

This was probably introduced when I simplified some of the backend code 
and I can honestly say that I didn't test the CSV functionality :/

I fixed it in subversion and a new release is imminent.

The dstat_app plugin currently outputs ANSI characters in CSV, which is 
something that is still to be fixed.

Kind regards,
