waking up from suspend makes all tabs go blank

Whenever I put my PC into sleep and wake it up again (with Tabby opened), all the tabs go completely blank. It looks like HTML when you linked an incorrect image path. Newly opened tabs work normally. 

I'm guessing there is some sort of refresh function that needs to be running, which doesn't when you wake up from sleep?

I'm using 1.0.227, Linut Mint, X11
