So as a lex/yacc/sip neophyte, I'm hunting down the problem as best I
can, and here's what I have so far:
While parsing qpaintdevice.sip and qtbitmap.sip, the parser calls
findIfaceFile(). While parsing qtbitmap.sip, it also calls
appendToClassList(). Those are never called while parsing qpixmap.sip.
Going further, I've instrumented every instance of which sets an
iff->module (which is null for QPixmap, causing this error), and none
are called when parsing qpixmap.sip.
So there is a problem with sip and/or qpixmap.sip, such that sip is not
getting any classes/modules from qpixmap.sip. Something is broken.
