Sometimes, I do get those errors.

But if I take a working piece of python and stick in a sabotage statement

Var1 = var2

Where var2 is undefined (i.e. has never been assigned anything)

Just silent failure.  No error.

Syntax errors for external methods can also be found by clicking on the 
'Save Changes' button of the external method object when in the ZMI.

Referring to non-existent python variables (eg. the mistyping you described 
above) should raise a KeyError.  Do you have any try/except statements in 
your external method which may be capturing the errors?
