Any QT application crashes on opening file dialog. When I try to open file dialog first time it opens after 10 seconds and I can choose file in it. When I press Cancel and trying to open it again application crashes.
Hello.... I have found the problem. This is QtProject.conf file in ~/.config directory. It size was more than 1 Gigabyte. Something goes wrong in some Qt application and this file was corrupted. QFileDialog class loads settings from this file and crashes with std::bad_malloc.
