Public bug reported:
Binary package hint: gdm
Applications that require Tk support do not work if logged into a
machine through XDMCP. They do work if logged directly into the machine.
A simple example is idle, the python shell. This is what happens if
logged into a machine via XDMCP:
a...@wilde: ~ $ idle
Traceback (most recent call last):
File "/usr/bin/idle", line 5, in
main()
File "/usr/lib/python2.6/idlelib/PyShell.py", line 1386, in main
root = Tk(className="Idle")
File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1646, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable tk.tcl in the following directories:

"source /usr/share/tcltk/tk8.5/tk.tcl"

"uplevel #0 [list source $file]"
This probably means that tk wasn't installed properly.
Last sentence still belongs to the output. Tk is installed properly as
it works if in a straight X session.
