This problem MIGHT BE SOLVED. I cross my fingers!
I tried to analyze what happens. The following is seen when typesetting
[campbell:92] with a crosslink to [crypto92]:
> Parameter <campbell:92> on bibgetvard\pbd:campbell:92
> ------ crossref crypto92 -------- CALLED FROM \bib@crossref#1

! Missing \endcsname inserted.
I can see that \bibinsertcrossref gets the proper reference because the defined
variable is: @@pb@crossref=crypto92
Experimenting on \bibinsertcrossref (inside \unprotect-\protect):
Redefine \def\bibinsertcrossref#1#2#3{\cite[crypto92]} CITE WORKS!
But redefine: \def\bibinsertcrossref#1#2#3{\cite[\@@pb@crossref]} CITE GIVES AN
ERROR
The redefine:
\def\bibinsertcrossref#1#2#3{\edef\tmp{\@@pb@crossref}\cite[\tmp]} CITE WORKS
Therefore I propose to change the definition of \bibinsertcrossref to:
\def\bibinsertcrossref#1#2#3{\bibdoifelse\@@pb@crossref{\edef\tmp{\@@pb@crossref}#1\cite[\tmp]#2}{#3}}
