Most executables crash when running in GUI but not in terminal

Most of the executable ELF files in /usr/bin/ will not run from any GUI interface and most do not show up anywhere including in the files list. When I try to execute one from GUI I get the popup box that I have attached to this report. However, when I run the same file from a terminal it will open and run as it should. It would seem the error is either in the GUI or every single ELF file is missing a : in the uri. Many of those are supposed to run in the background. They don't. I will be very happy to see this fixed and everything running as it is supposed to run. Just in case my attachment has something wrong with it too, I will type out what is in the popup box:
Invalid url:'/usr/bin/gnome-system-monitor' given, exiting No ':' in the uri
