LrShutdownApp invoked at the wrong time on Windows

Question

Documenting for future reference: LrShutdownApp is invoked when LR is shutting down. But on Windows, when LR exits and starts a backup, it first puts the API into some kind of shutdown state, where calls return the error "Attempt to make a request on a closed server." Then it calls LrShutdownApp, which is too late.

The workaround is to wrap the background tasks with LrTasks.pcall() and just ignore that particular error.

"Hi, I had that error with the plug-in LogiOptions, I disabled it and the error does not occur." Logitech installs (or installed) that plugin as part of its general utilities, whether the user asks for it or not -- most people aren't even aware that it gets installed. Unfortunately, the plugin has a number of problems that Logitech has never bothered to address. [Use the reply button under the first post to ensure replies sort properly.]
