[Debichem-devel] Bug#709306: pymol: Crashes when running within xrdp/vnc (no 3D support)

[Petter Reinholdtsen]

Package:  pymol
Version:  1.5.0.1-2
Severity: normal
User:     debian-edu at lists.debian.org
Usertags: debian-edu

Dear Maintainer,

I discovered this problem when testing Debian Edu Wheezy with xrdp.  We
provide the Debian Edu desktop via RDP for Windows and MacOSX clients
using xrdp.

When trying to run pymol, it just crashes before showing any window.  To
replicate, install pymol and xrdp in Wheeezy, log in using 'rdesktop
rdpserver' on the machine and start pymol from the menu.  I tested using
Gnome.

When starting it from a terminal, I got these error messages printed:

  freeglut (pymol):  ERROR:  Internal error <FBConfig with necessary capabilities not found> in function fgOpenWindow
  X Error of failed request:  BadWindow (invalid Window parameter)
    Major opcode of failed request:  4 (X_DestroyWindow)
    Resource id in failed request:  0x0
    Serial number of failed request:  27
   Current serial number in output stream:  30
   PyMOL: abrupt program termination.

I suspect the cause is that pymol do not handle displays without 3D
support very well.  I believe it should show a popup stating that it can
not work with the current display setup, instead of just crashing.
