Segmentation Fault on exit

I’m using Qt on an am335x Starter kit Everything works good but when I close the application I get: Remote process started. bash: line 1: 2527 Segmentation fault DISPLAY=:0.0 /home/ubuntu/pippo -qws Finished running remote process. Exit code was 139. I get this error with any application, but if I run the application with sudo everythings works ok except for the touchscreen… I do not post the code because I get this error even with a “new project” without adding any lines of code.
