Yes. At least, this line can cause a "KeyError", even without
assuming that we have a very strange "__dict__".

On the other hand, when you look at the code in "DTMLMethod",
you will see that deleting 'validate' is controlled
by the local variable 'first_time_through".
And "first_time_through" is set to "1", if 'validated' was
defined by this call and to "0", when 'validated' was
already there.

Thus, locally, this looks quite safe.
This implies that what you see indicates that something
non-local is tempering with the "DTMLMethod"'s 'validate'.

I cannot tell you what this "non-local" is but
I have a workaround for you (you must modify the code, however).
You can prepend an "if 'validate' in self.__dict__:" before
the "del self.__dict__['validate']".
