+++ This bug was initially created as a clone of Bug #4945 +++
When trying to run any gtk app (so it seems, due to the pangocairo, cairo
dependency) on my Tektronix Xterm, the app crashes as the window attempts to
map. This does not happen on Linux-Linux remote X11 (DISPLAY=host:0.0), just
Linux-Xterm (DISPLAY=xterm:0.0). Below is the stacktrace of running gcalctool,
but every other GTK app I run dies the same way. I first discovered this after
upgrading to dropline-gnome 2.12 and tried to login to the xterm via GDM.
Program received signal SIGSEGV, Segmentation fault.
