Karl and Reinhard, you were right: indeed this was not the problem with
"fixed" font, but with p5-Tk without fontconfig support.

FreeBSD port by default (and eo ipso FreeBSD p5-Tk package) provide
non-fontconfig version because p5-Tk README states that "freetype2,
fontconfig and Xft is provided for Unix" as "experimental".

So, if I pass WITH_XFT=yes to the port's Makefile, tlmgr window looks
just like Reinhard's:

  http://anthesphoria.net/FreeBSD/TeXLive-Devel/translations/tlmgr-gui-FreeBSD-Xfce-20100204-WITH_XFT.png

Various Linux distros obviously all tacitly compile p5-Tk with XFT. I
guess that adding an info about that in tlmgr and on the web would be a
good idea.

Now answering your questions:

I found the cause: SCIM daemon (scim -d) running without XIM_PROGRAM
variable blocks tlmgr. At least on FreeBSD, other Tk applications
have the same problem. (IBUS daemon does not block Tk dialogs.)

I will investigate this further. For now, this solves the problem:

  export XIM_PROGRAM="scim"
  export XIM_ARGS="-d"

With p5-Tk / WITH_XFT:

  preset settings:
  -weight -> normal
  -underline -> 0
  -family -> undefined
  -slant -> roman
  -size -> 0
  -overstrike -> 0
  actually used settings:
  -weight -> normal
  -underline -> 0
  -family -> Bitstream Vera Sans
  -slant -> roman
  -size -> -15
  -overstrike -> 0

Without XFT support:

  preset settings:
  -weight -> normal
  -underline -> 0
  -family -> undefined
  -slant -> roman
  -size -> 0
  -overstrike -> 0
  actually used settings:
  -weight -> normal
  -underline -> 0
  -family -> fixed
  -slant -> roman
  -size -> -17
  -overstrike -> 0

I am aware of it... Just one of testing tree/bins combinations I use.

(FreeBSD) It is the last p5-Tk version (804.028).
