Hi
Can't reproduce it with my window manager, application resizes to any size fine here. Looks like yours is not giving QMPDClient right hints about its size.
However this problem have been reported already. I'll try to think of something, in meanwhile I suggest filing a bug report against your WM.
Yes, I understand. It's window manager problem. Here's QMPDClient under ion3, resized into very small window (767x331): http://dump.bitcheese.net/files/ehebyni/small-qmp.png
