Misleading error message if snippet returns null

Summary

When a snippet returns null, the error message shown in the browser states that the corresponding method could not be found. This is somewhat misleading. I think it would be more informative if it were changed to something like snippet.method returned null. I have uploaded a small project showing this error at https://github.com/aweinert/liftweb-null-snippet.

What I did

$ git clone https://github.com/aweinert/liftweb-null-snippet
<...snip...>
$ cd liftweb-null-snippet
$ ./sbt
> container:start
<...snip...>

Then, open a browser and navigate to 127.0.0.1:8080

What happened

An error is displayed, as shown here:

What I expected to happen

An error should indeed be displayed, but I think the error message is somewhat misleading.
While it is probably technically correct, it should point to a null-pointer-issue rather than to a method resolution one.
