You are right, this actually sounds less than useful and it is surely
not the way it is supposed to be. I cannot reproduce this here (debian
lenny, Python-2.5.2, Tk-8.4.19) though. I guess this is most likely a
bug in your version of Tk.
I wrote a tiny tcl script that does basically the same as the python
code from my last post, you can try if it exhibits the same bug, then
we could at least be sure that it's not python that causes the bug.

###CODE###
 #!/usr/bin/env wish

toplevel .t
wm withdraw .t
wm protocol .t WM_DELETE_WINDOW {wm withdraw .t}
button .t.b0 -text "filedialog" -command tk_getOpenFile
pack .t.b0 -padx 100 -pady 100
button .b1 -text "popup" -command {wm deiconify .t}
pack .b1 -padx 100 -pady 100
###CODE###
