R devel - Apr 2003 - sweave provoked segfault (PR#2809)

This problem is with R 1.7.0 (as released) on Linux and Solaris. Details below
are from Linux, Mandrake 9.1. The problem also happened with R 1.6.2 and on
Mandrake 9.0.

Vignettes often (for me) provokes problems with the misleading error message:

* creating vignettes ... ERROR
Error in sub(pattern, replacement, x, ignore.case, extended) :
        invalid argument
Error in buildVignettes(dir = ".") : Error in sub(pattern,
replacement,
x, ignore.case, extended) :
        invalid argument
Execution halted

This becomes a segfault with gctorture(). Output from gdb bt is copied below.
