If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result:

20:32 ~ speter > Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden

(English: "File or directory not found").

Can anyone explain or knows a workaround?
