Can't use Help menu

[Kcchouette]

When using the deb version clicking "Help">"Source(svn)" or "Help">"Report a bug"/ changelog it's doing nothing.
On console log we have:

gio: file:///home/user/Downloads/@%F7%AF%C6%DAU: Error when getting information for file “/home/user/Downloads/@����U”: No such file or directory
gio: file:///home/user/Downloads/@%F7%AF%C6%DAU: Error when getting information for file “/home/user/Downloads/@����U”: No such file or directory

Sometimes we have:

xdg-open - opens a file or URL in the user's preferred application

Synopsis
xdg-open { file | URL }
xdg-open { --help | --manual | --version }
Use 'man xdg-open' or 'xdg-open --manual' for additional info.
