I have these two files test_project.pro ------------------------ TEMPLATE = app LANGUAGE = C++ OBJECTS_DIR = ./build MOC_DIR = ./build DESTDIR = ./ CONFIG += qt warn_on release thread SOURCES += main.cpp\ ------------------- and main.cpp ------------------------ #include <QApplication> #include <QFileDialog> #include <QMessageBox> int main(int argc, char *argv[]) { QApplication app(argc, argv); QString fname = QFileDialog::getOpenFileName(0, QString("Open file"), ""); QMessageBox::information(0,"test","You selected file: "+fname); return 0; } ------------------------- Can it be any simpler? it compiles with qmake && make && ./test_project and running it crashes!

Try installing gdb, run your program in the debugger, and get a backtrace. That will show why the seg fault is happening.
BTW, your program compiles and runs just fine with me, and I'm using Qt-4.3.1-r1 on my system. I'd say it's a local issue. Using gdb is your only hope here, I'm afraid.
I did gdb test_project to run it and got this result: Starting program: /tmp/test_project (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols

[Switching to Thread -1228182640 (LWP 7753)] 0xb7f78410 in __kernel_vsyscall () (gdb) Any ideas? I'm not good at using gdb or understanding it.
add debug to your CONFIG line in your .pro file and rebuild your program. Then when you run it in gdb, and get to the prompt, do "bt" to get a backtrace of the error.
You may need to rebuild Qt with the debug use flag also to get any useful information. Your cflags might be causing some issues as well. There may be something wrong with the Qt compilation with your particular cflags. You might try rebuilding Qt with barebones cflags to see if that fixes your issue.
Thanks for your gdb suggestion: here is the output I go (see below) I will as soon as possible rebuild Qt with debug flag and post result.

sorry, I don't see anything more useful here. I woudl recommend you try commenting out some lines of your program to see if there's a specific line that's causing the problem. I also recommend you take this to forums.gentoo.org, where more people can be of much more help.
