double QLabel declaration problem

[spirit]

This problem appears even without using secondlabel in program, that's why it seems to be strange for me:/

Show us cpp file.

Or even better: Just debug your application!

As I said, problem appeared even without anything in cpp file. But I solved it. I made new identical project, copied code from all files and compliled it... and now it works. I don't understand it, but now it doesn't matter. Thanks for help
