"General fields" settings not applied with Bibsonomy plugin

[Former user]

Reported by nicoj: Not sure whether this is your bug or Jabref's. I've submitted it for both...

Changes to the Jabref's "General fields" settings are ignored / reset with the Bibsonomy plugin installed (Bibsonomy plugin changes them on install). They are used as long is Jabref is not restarted, but on restart everything goes back to the new default settings. Changes are remembered / observed without the plugin installed.

Using the Bibtex plugin 2.5.2, Jabref 2.7.2, Windows 7.
