Lintian tag information: desktop-mime-but-no-exec-code (type: warning)
Description (from lintian-explain-tags)
The named desktop entry indicates support for at least one MIME type, but does not provide a code like %f, %F, %u or %U in the Exec key. If the application can in fact handle files of the given MIME types, the menu item should somehow pass those filenames as parameters to the executable.
