Install latest rc proposed on a nexus 4.
Attach a bluetooth mouse - this triggers windowed mode.
Orient device in landscape
Open weather app - which is locked portrait in the .desktop file

Shell rotates to become portrait and there's no way to get it out of that mode easily.

The shell should probably ignore the .desktop setting which says that an app is portrait only if it's windowed.
