Which qt4 program crashed? Please be more verbose...

You forgot to reopen...
(In reply to comment #3) > You forgot to reopen... Reopen what? I test on qtconfig(qt4) programm too.
on X.org 2.8.99.13 too...
I just compiled your program and it works just fine here. Are you using the Qt4 in portage? Are you using the latest version? Are you sure you are linking against the proper Qt 4 libraries at run time?

'ldd your_program_name' will show you which libraries it links against
Also, what command did you use to compile it? Do the demos/examples that come with qt work? (you have to use the examples USE flag when emerging to get them installed)

No but, this bug in designer too!!! makefile i creat qmake tools.
shrug - i cannot reproduce it
