You appear to be upgrading from gvfs 1.8.2-2 (2011) to 1.28.2-1.  1.8.2 is
older than oldstable (Debian 7, wheezy), which has 1.12. Were you upgrading
directly from squeeze (Debian 6) to stretch (the future Debian 9)?

Debian does not support upgrades larger than one stable version
(approximately 2 years of development). If you have a very old system
with testing or unstable, you should upgrade to the corresponding stable
release, then upgrade through stable releases until you reach current
stable (Debian 8), *then* upgrade to current testing.

Most maintainers actively remove the metadata that would be needed for
upgrades across more than two stable versions, because it makes the
dependency solver's job harder, which can cause supported upgrades to
fail or take a very long time. The relevant changelog entry here is

  * Drop obsolete Breaks/Replaces/Conflicts from pre-wheezy.

in version 1.24.1-2.
