           Summary: GTK Apps crash on remote X-Terminal
           Product: cairo
           Version: 1.0.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: nate.byrnes at gmail.com
         QAContact: cairo-bugs at cairographics.org

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.
