"Failed to register input channel" - what is this caused by and how to fix this?

I've been getting the following error, reported via Market developer console by the users of my app:

java.lang.RuntimeException: Failed to register input channel. Check logs for details.

Italicized lines are part of my code. The code in question just creates and shows a dialog. It is run from a Runnable posted to a Handler. Everything should be happening in the GUI thread (that's why Handler is used).

I don't know how to debug this. I haven't experienced this problem myself, and all I have is just a bunch of automated reports. Google shows up a couple of threads on this exact problem, but no answers (except a hint of this being an Android 2.3.3-specific problem).

This may be a Launcher Pro issue. LP is a home replacement. It appears Launcher Pro does not release some resources as it should. Check out this answer here
