    Fix innocuous bug
    
    Fix bug introduced in GParted 0.9.0 in commit
    4a8fef98225c513cad9d38f32303c67d1ceed4b8 to address ISO C++ ambiguity
    compiler warning.
    
    Due to the nature of the surrounding code, this bug was not evident
    in the log file output.
    
    Thanks to Magnus Fromreide for finding this bug.
