When a file is specified as application-start parameter, Kdenlive assumes it to be an XML file (project). My petition is to check MIME-type and, when it is not detected as XML project, create an empty one and add specified files as project's elements to work on (eg. video clip).
This would help for a quick click-and-edit task from OS file browser.
