[PyQt] Pointer Attribute

[Jay L.]

Thanks for the suggestion to use the Force version.  Much cleaner.

Inside of %SetCode, it does not appear that the sipErr variable is
available.  I tried simply replacing the argument with `int err;` and then
`*err` in the signature.  Still segfaulting.

Any other suggestions of what to check?  My next test will be to move this
code into get and set methods to have access to sipErr, but perhaps
something else could be causing this?

(The previous code is unchanged except the final arg 0 is replaced with
*err.)

Thanks for the assistance,
J
