gtk apps crash with badname error

[Leo Zhadanovsky]

I just upgraded from Hardy to Intrepid. This is what I get when I run most GTK applications:

/usr/share/themes/Human/gtk-2.0/gtkrc:273: Unable to locate image file in pixmap_path: "panel_bg.png"
The program 'pidgin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadName (named color or font does not exist)'.
  (Details: serial 255 error_code 15 request_code 45 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
