Is that the complete crash log?

Can you try refreshing individual feeds to see if a particular feed may be causing the issue? You can disable the automatic refresh with this:

defaults write uk.co.opencommunity.vienna2 CheckForNewMessagesOnStartup -bool NO
defaults write uk.co.opencommunity.vienna2 CheckFrequencyInSeconds -int 0
