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):
Thread 1 "x64" received signal SIGSEGV, Segmentation fault.
