GnuCASH-2.2.9 crashes when saving a custom report

[RandomUser]

As noted in the following bugzilla report, changing to slib-3b1 fixed
this particular problem.

Unfortunately, there were a few complications in installing slib-3b1,
some of which are noted in the following online comment.

A PR to update SLIB has been submitted.

When I was finally able to install slib-3b1, recompile GnuCASH-2.9.2,
create a new Custom Report - I was then able to successfully SAVE the
report (via "File/Add Report") and GnuCASH did NOT crash!! The new
report was also saved!!!
