I must correct my previous statement. The problem occurs also with 1.5.1.
I guess it has to do with Fedora Linux.
Here are some versions of libraries:
XFree86: 4.3.0
Xft: 2.1.0
fontconfig: 2.2.1
gtk: 2.2.4

The problem is solved.
I had TrueType AND PostScript version of the Symbol font installed, and
enabled the TrueType flag for Symbol in fontEncoding.properties. This
obviously resulted in some confusion. The Type1 font removed,
it worked well again.
Isn't it possible on Linux platforms to use a shipped font, like
URW Standard Symbols L?
Another question: How do I find out what font is used for a specific character.
For example 𝔐 is very ugly, and I have not been able to find out the
font used.
