Which include files do that is consistent, but reordering the includes sometimes changes which are affected, apparently randomly.

Thanks. The QTCREATOR_DUMP_FILENAME_WHILE_PARSING mentioned in that ticket gave me exactly what I needed to track the problem down.

qmake and Creator are parsing my .pro file differently, and Creator failing to include another configuration file - even though there's nothing relevant in the included config file - caused all the other misbehaviour.

(I'm not sure whether it's a bug in the config file or in the .pro parser in Creator yet - if it turns out to be the latter I'll open a bug).

Cheers,
