Copy and Paste Bug in 4.5.3

I'm on Pycharm 4.5.3 on Ubuntu . Paste operations from other applications  to pycharm works well but it seems to fail vice versa. Similarly within pycharm  window simple Ctrl+C and Ctrl+V doesn't seem to work.

I have to paste-from-History every-time and it is annoying. Is there a know fix for this issue ?
