As you wrote, this fixes the symptom rather than the actual cause and it 
might be error prone to relax error checking there.

The issue is (most probably) caused by an outdated Fluid cache. That 
gets flushed whenever a template was changed, but it's not if only the 
PHP code of a used ViewHelper was modified.
We should probably fix that instead.

Besides, you raise another good point: When updating the cache should 
always be flushed – we should add that to the release notes, or (if 
easily doable) do that automatically.
We had some other reports that suggest an invalid cache.
