Ok, backtracing was easier and more fun than I expected. I tried it two times:
Program received signal SIGSEGV, Segmentation fault.

Program received signal SIGSEGV, Segmentation fault.
XkbHandleBell (force=0 '\0', eventOnly=0 '\0', kbd=0x8273488, percent=50 '2', pCtrl=0x8273cc0, class=0 '\0', name=0, pWin=0x0, pClient=0x86a9270) at ../../xkb/xkbEvents.c:404

Line 404 in xkbEvents.c
would be:
xkbi = kbd->key->xkbInfo;

Interestingly, the crashes happen only if the Wacom is connected during the server start. If it is removed later the server still crashes and if the Wacom is added later it does not (however it then is less usable).
I hope this helps.
