Doesn't help.

But here is some more info:

1) This is under Windows (tiny detail I forgot to mention before ;-)

2) This does not happen if I start by setting a default font (Config->Set
default display font)

3) If I don't set a default font, I get the problems in several ways

  a) add text layer ; type some text ; display ; click on font selection
  b) add text layer ; type some text ; add second text layer ; type some
text; display
  c) idem for any combination of layers containing fonts (e.g. add one
barscale and one grid)

Hope this helps finding the problem.
