Okay, I have traced this to the file pgfsys-dvips.def, where you have 
statements like

    /pgfsc{}B% stroke color is empty by default

In other files in the same TeX directory, this line reads

    /pgfsc{} bind def% stroke color is empty by default

If I do search-and-replace "}B" for "} bind def" in pgfsys-dvips.def and 
rerun latex on 1lyxpreview.tex, the error disappears. I've seen error 
messages from xdvi that seems to be similar to this, and queries on the 
internet about this. This should probably be reported as a bug on 
http://sourceforge.net/projects/pgf/, but I am reluctant to do that 
since I do not use the package myself.

Possibly dvips understands "B" as "bind def", I do not know. There is 
certainly no header included in your file that defines "B".

Would you report this, Jürgen?
