Sorry to add to the confusion Yes I have a /usr/share/icons/ folder but I do not have a /usr/share/icons/customicons folder. I am running Hardy,  AMD64. 
Setting the export LIBXCB_ALLOW_SLOPPY_LOCK=1
produces:

vmware: ../../src/xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.

I have added the libx11-noxcb to /opt/LIBx11-noxcb and would like to know how I change the script /usr/lib/vmware/lib/wrapper-gtk24.sh to make vmware work.
