Comment 1 for bug 22772

The error seems to bei in Utils.h:

inline Glib::ustring num_to_str( Sector number )
{
 std::ostringstream os;
 os .imbue( std::locale("") );
 os << number ;
 return os .str() ;
}

this is used by the GUI as well as by the actual resize-function, where the
formatting makes no sense. Commenting out that line

// os .imbue( std::locale("") );

makes the partition list in the GUI look a bit less pretty, but at least
shrinking works then.

This is not relevant for growing, as no size parameter is handed then at all to
the filesystem resizer.
