Comment 3 for bug 1588659

Just because this happens with "program[s] like xpad" doesn't make this an xpad bug. The xpad package (both in the previous and the latest version) installs its desktop file using the standard methods provided by debhelper. Such entries consistently not showing up in the menu until after a new login while they do appear in a menu editor is likely an issue or design choice of your desktop environment.

Unless you can demonstrate this bug is specific to the xpad package only, please reassign to the "common denominator" (probably the desktop environment or -less likely- debhelper).
