Thank you Kyle. I created a basic example as you suggested - a simple application linking a simple static library, both incorporating a header containing Q_OBJECT - and to my great chagrin it worked perfectly, without any compilation errors. 

So it seems that I've been wrong to suspect this as the cause of the multiple-definition errors in my main project. Clearly I must dig deeper, and if I find that the final explanation is of general interest then I shall report back.

Stephen.
