"/" is a special character in Jess. In particular, two "/" characters
delimit a regular expression, which can't actually be used the way
you're "using" it. That symbol consisting of a single double-quote is
the (admittedly strange) way that Jess has interpreted what you've
asked it to do.
In any case, recent versions of the manual take some pains to mention
that file paths must absolutely be written as quoted strings in Jess;
i.e., this does what you want:
Jess> (explode$ "679196dc49add8e88a07bd9fd34ec2f7 \"/a/b\""))
(679196dc49add8e88a07bd9fd34ec2f7 "/a/b")

I do not understand why this explode$ differently in those two cases.
