Bug#286012: new gnucash dropeed the guppi dependency

[Stefan Huehner <stefan@huehner.org>]

Hi,

the gnucash version 1.9.6-1 (currently in incoming) dropped the
dependency. As gnucash was the last pakage depending (and
build-depending) on guppi.

Please consider removing this package after double-checking the
dependencies.

Regards,
Stefan
