Hi all!

I am struggling with a problem that I have never seen before. I need to declare 14 QStrings but I can only declare 7, because as soon as I declare 1 more my code crashes at the beginning.

As you can see some of my QStrings are commented because I can't run the program if they aren't.

If it helps I am using Eclipse Helios with qt 4.5.0 on ubuntu 9.04 32 bits.

Thanks
