I can reproduce it on 2 machines. One a desktop, one a laptop.
Both run the same Kubuntu version, have more or less the same configuration.

Since my report is marked as related to/duplicate of another, it's not just
me that has this...

Maybe the problem is keyboard (keyup/keydown/onkey events) related. 
Keydown caught in project inspector, transferred to mainform (or wherever) for processing, 
keyup caught somewhere else, command again executed.
Something like that.

It doesn't happen when I select the compile item from the run menu. 
That would support this theory.

Anyway, I will test tonight with your new define. 
We'll see where this gets us. Thanks for looking into this.

Michael.
