Affects Versions: 1.0
Environment: Windows XP, JRE 1.4.2

This error is easily replicated using the attached project vssproviderbug.zip.
Unzip the archive and run
{code}
mvn scm:changelog -DvssDirectory=something -e
{code}
Assuming the file ~/.scm/vss-settings.xml does not exist, you should see the
above error in the stack traces. Note that you don't need VSS installed (or
even to be on Windows) in order to replicate the error - Maven doesn't actually
get as far as making a call to ss.exe.
