NullPointerExceptions when ATerm editor is initialized.

When running any builder that outputs a .aterm file, I get the following NullPointerExceptions in the console of the debugger-Eclipse.

The editor works ok-ish after that: syntax highlighting is present, but clicking the “Transform” button brings up a “Could not load builders” error.

At the moment I’ve no clue which recent change might have caused this.

Probably caused by my observer syntax change, I’ll add an exception for old editors.

Actually there is already an exception there.. this would mean that it cannot find a SemanticObserver at all?

Possible fix in r24601, let me know if that fixed it.

That fixes it, thanks!
