Sid, legacy nvidia 340.108 driver ruins running Qt software

Hi)

Debian Sid.

With nouveau all working good. But after installing legacy 340.108 nvidia driver for my gf9800 i have Segmentation Fault at launching all Qt GUI software. And opposite, Qt works again after uninstalling nvidia driver.

But very strange that if i run Qt soft via debugging tools such gdb or strace i have no errors.

Code:

gdb ./doomseeker

strace ./doomseeker

Same is with Qbittorrent

and 2048-Qt

Only one Qt application starting normally - CMake GUI

Segmentation fault

Code:

#include <QApplication>

int main(int argc, char **argv)

{

  QApplication app(argc, argv);

  return 0;

}

Is where way to solve this?
