run time error

[Werner Scheinast]

Hi,

when I want to parse an arbitrary file, e.g. the following single line ...
        {a a a2 a a4 a a1 a}
... I always get an error like this:

I have the suspicion that this is not a bug in Lilypond, but that one of 
my libraries is broken. Does anybody have a clue where/how I could search?
What are those mysterious files noteheads.s0 etc.? They are not among the 
installed files, so they are probably created dynamically.

What could be wrong?
