This can happen in a number of cases:
- the package it belongs to has been uninstalled
- the package it belongs to has been upgraded, in which case it is
likely that the desktop file has been removed and a new version of
it has been installed in place of the old version
- the file has been written to using an editor that first saves to a
temporary file and then moves this temporary file to the
destination file, which effectively results in the file being
temporarily deleted (vi for example does that, whereas gedit
doesn’t)
In the first case, we want to remove the application from the
launcher. In the last two cases, we need to consider that the desktop
file’s contents have changed. At this point there is no way to be
sure that the file has been permanently removed, so we want to give
the application a grace period before checking for real deletion. */
