Could be that too, yes.

RuntimeError is normally used to communicate a program logic abnormality. It
conveys similar information to an ASSERT, although in a different manner.
This Qt method returning NULL is perfectly normal (although the qt
documentation doesnt state that :-(. The nature of the error is different to
"Underlying C/C++ object has been deleted", so RuntimeError felt suprising.
I anticipated either a return value of None, or an exception derived from
ValueError (indicating that the value of the style name is wrong).
