Error message on startup

[DavidHB]

The complete message was as shown; the containerID was not specified, or was null to begin with. So I am afraid I cannot provide the ID.

I was experimenting this morning with Lumin on Android, which crashed on initial startup, but then did function. (I know others like it, but I am afraid that it does not impress me.) From what you say, that event may relate to this error message.
