Bug#593354: fldigi vs. xmonad: still a problem in fldigi 3.22.x?

[Mike Magin <mmagin@lowerarchy.com>]

Hi Kamal and maintainers,

I'm on jessie on amd64, fldigi 3.22.01-1 and xmonad 0.11-9.

It is pretty easy for me to reproduce the bug.  All I need to do
is have a workspace in the Tall mode, have a couple other apps
windows open, position fldigi in the large space to the left,
open the Signal Browser from the menu, and it's stuck.

Making xmonad float all the windows of class Fldigi seems to
prevent the problem, as previously mentioned.

Nearly all of my Linux programming experience is non-GUI,
so I'm not sure I'm in a position to fix this myself, but 
I am perfectly happy to help test fixes, etc.

Thanks,
Mike, AG6ET
