I realised that the problem appears when I am using the knitr module (but not always). I now found a workaround which is to have an empty master document which does not contain the knitr module — and which then contains the actual document with the knitr module via \input.
I still need to construct a simple example to make the error reproducible. @Joel: I think I had also experienced the error in earlier LyX versions. Best, Uwe On 16.

Try using myfigures and mytables or something like that and see if this changes things.
