History synchronization broken
Tried version 1.1.2 on Win 7 x64 (although the story on Ubuntu is similar), started with a blank config. Added my account as usual - history sync was not triggered automatically, at least I didn't notice any activity suggesting this on the server. Then I tried Accounts->Advanced->Synchronize History->Everything. XML console shows this and syncs nothing:
4/2019 11:44:59 PM --> 2019-02-24T21:44:56Z 0
As a contrast - I'm running 0.16.9 on Linux and syncs history perfectly with the same server. About the same version on Windows was syncing fine too (but had to ditch it because of Python problems causing a crash).
Prosody version: 0.10 nightly build 500
