Full crash backtrace

I have just started and logged into my Matrix account and then when rooms and all should start loading it crashed. When I relaunch it and select the existing account it also just crashes when it should display rooms.

STEPS TO REPRODUCE
1. Login with existing account (I have it on matrix.org)
2. proceed to loading rooms and all

OBSERVED RESULT
NeoChat crashes and this is shown in the konsole:
