    general: Fix the error dialog not showing
    
    Since commit c1bb594d, a dialog error wouldn't be shown if
    there was an error when renaming a file or setting permissions
    to a file.
    
    The user should be informed through a error dialog if something
    went wrong in the above-mentioned use-cases.
    
    This patch solves the issue by using the parent, instead of NULL.
    
    Closes #705
    
    
    (cherry picked from commit 569c1acecbe01815a98cd42cfca5a4840b0e2754)
