Mycroft freezes when saying two things in a row (rspi2)

hi there,

I’m running mycroft-core on archlinuxarm with pulseaudio on a raspberry pi 2.

Everything works fine and he is recognising my input and responding to it. I can then ask another question and he will respond again. The problem is when I ask something that requires him to say two separate sentences, like “what’s the weather”. He will say the first phrase
It's currently clear sky and 26 degrees fahrenheit in Lawrence, Kansas. and then he is supposed to say the second phrase Today's forecast is for a high of 27 and a low of 23 but it’s never uttered without any error message. After 20 minutes of waiting I restarted mycroft-voice and it works again.
This is the log:

any idea what I could do?
