[Pkg-tcltk-devel] Bug#1021389: tcl-ttkthemes: When this is installed, tclsh 'package require Tk' fails with circular dependency error

[Patty]

Package: tcl-ttkthemes
Version: 3.2.0-1
Severity: grave
Justification: this renders another package 'tclsh' unusable, as well as this package itself

Dear Maintainer,

When this package is installed, 'tclsh' (the Tcl interpreter, provided by debian package 'tcl') becomes broken in such a way that it's no longer possible to import/load the Tk graphics/gui extension (provided by debian package 'tk').

Although I'm reporting from a Debian Stable system,
this bug is happening in Ubuntu too,
and this package seems obscure so I assume this may still be an issue that nobody else has noticed or fixed yet.

Steps to reproduce:
 0. Start a X windows/desktop session.
 1. Install debian packages 'tcl', and 'tk', and 'tcl-ttkthemes', perhaps with this command or similar:
sudo apt-get install tcl tk tcl-ttkthemes
 2. Create a text file with the name 'test.tcl' and put these lines in it:
package require Tk
pack [ label .l -text "Debian" ]
 3. Open a terminal window and run this command:
     tclsh test.tcl
 4. Observe that this error message is printed and the script exits:
circular package dependency: attempt to provide Tk Ϻ£ü requires Tk
    while executing
"package require Tk"
    (file "test.tcl" line 1)
 5. Uninstall debian package 'tcl-ttkthemes'.
 6. Run 'tclsh test.tcl' again, and note that this time the error is not printed and the script opens a window with text "Debian" in it.

Thank you
