[Pkg-lxde-maintainers] Bug#852316: lxpanel: stale menu entries when desktop files modified

[Jonathan Dowland]

Package: lxpanel
Version: 0.9.2-1
Severity: normal

Dear Maintainer,

lxpanel continues to list menu entries for applications even after
/usr/share/applications/whatever.desktop has been removed.

On startup, lxpanel appears to create ~/.cache/menu/<something>, which
corresponds to the state of /usr/share/applications at that time.

However it does not appear to reliably refresh this cache. If I delete
something in /usr/share/applications and restart lxpanel, the menu item
remains present.

(It does seem to handle entries being added, however.)
