So, that all looks pretty bad, as if something very seriously wrong on this system.
First major problem:
QOpenGLShader: could not create shader video driver isn't functioning properly
second: Thread 4 (Thread 0xacd01b40 (LWP 1492)): #0 0xb7fd5d21 in __kernel_vsyscall () Backtrace stopped: Cannot access memory at address 0xacd0100c
never seen that before, but if kernel calls are failing preventing debugging, there's not much we can do.
May be worth trying a fresh/clean f28 live image, and see how that works for you on this system. If better, may be worth re-installing.
