Unable to retrieve queue and history items from Nzbget

seems to be related to this issue:

"System.ObjectDisposedException: Cannot access a disposed object." On manual NZB grab

My problem started when I upgraded mono, as far as I can remember from 4.4 to 4.8 after Jackett informed there was a problem with my current version. I now have a trace log, however since it contains sensitive information I’d rather email it to devs rather than post it online.
