possible bug for powertop 2.0-0.2

[Laurent Debian <laurent.debian@gmail.com>]

Hi all, 

Since it would be my first "bug report" I am writing this before I make someone to loose his time. 
Here is the problem : 
I am experencing an (old) bug with powertop : 
On battery if I launch powertop I get a crash with 
>terminate called after throwing an instance of 'std::ios_base::failure'
>                                                                         what():  basic_filebuf::underflow error reading the file
>                                                                                                                                 Abandon

And everything works well on AC. It was a well-known bug in the past but I think (juste coming back to debian after 10 years ...)  it has been resolved and it reappearing here ? 
Should I report a bug or not ?
