Problem to execute file command

[GoogleCodeExporter]

When I load my picture with timthumb.php, I have an error in my apache logs
but the picture is ok.
ie:

==> /var/log/apache2/access_log <==

I have changed line 234
$mime_type = trim(@shell_exec('file -bi $file'));
with
$mime_type = trim(@shell_exec('file -bi "$file"'));

and I have no more errors

This should be updated in the source. This worked for me as well.

@grougrou & @fud.theturtle:
I don't think 'file -bi "$file"' works... $file is still in single quotes. I 
think 
this way you just get rid of the error message and it's still not working as 
intended.

The working solution:
$mime_type = trim( @shell_exec( 'file -bi ' . escapeshellcmd( $file ) ) );
