Where does it say error? :) It's just the backtrace at the time gdb attaches to the process, which implicitly stops its execution. At that point, enter

handle SIGUSR1 nostop

to make gdb ignore the signals involved in VT switches, then

continue

to continue execution of the X server. Then get the backtrace once it hits the SIGSEGV.
