Public bug reported: It seems, with Ubuntu 17.10/Wayland/64 bit at least, _all_ of the emulators within the VICE package (emulators for various Commodore 8 bit systems) crashes. All of them seems to be connected with XQueryExtension() somehow. I've tried x64 (Commodore 64 emulator), xvic (Commodore VIC-20 emulator) and xplus4 (Commodore Plus/4 emulator). With gdb, I got the followings (I didn't marked vice package as the bug "source", since it can be some other library as well or so):
