2.0.4 crashes on certain key press in putty

I have been noticing Whatpulse crashing many times on me this week and I found out that it crashes when I press ‘Page Down’ key on my keyboard multiple times.

It doesn’t seem to happen in browser or anywhere else. Just in putty when I have a SSH connection open to a server.

Does not happen with me, opened an ssh session to a couple of my servers (one local and one remote), i was using Win 8 x64.
