musescore sttop with 'Mscore: fatal error: cannot load internal font' on openSuse 12.3 linux

Summary: my assumprtion is that I have an incompatible version of the library than contains the QFontDatabase::addApplicationFont routine.

If I start mscore without any argument, I get

$ mscore
Mscore: fatal error: cannot load internal font

I peeked in the source code and found the fatal error comes from the following lines:

      if (-1 == QFontDatabase::addApplicationFont(":/fonts/mscore-20.ttf")) {
            fprintf(stderr, "Mscore: fatal error: cannot load internal font\n");
            if (!debugMode)
                  exit(-1);
            }

(This also explains why it more or less works with the -d option.)

With the -d option, it says

$ mscore -d
