dia breaks twm in Xvnc

[gregrwm]

twm works in Xvnc until dia is installed, after which twm no longer works in Xvnc.

installing dia also installs:
                  dia-common
                  dia-libs
                  dia-shapes
                  gsfonts-x11

this problem exists in precise, quantal, raring, saucy, and trusty.

workaround:
apt-get purge gsfonts-x11
(after which twm again works in Xvnc)

perhaps this should be retitled "gsfonts-x11 breaks twm in Xvnc" and reassigned to the twm package.
