    shell: Fix a crash when failed to connect to D-BUS daemon
    
    The patch checks for a null pointer in the code that was causing the
    segfault and instead of just returning from the dbus enabled open uri
    code falls back to the function that opens documents with dbus support
    when the program doesn't have a connection to dbus.
