Xpra: Ticket #1397: Regression: cannot minimise windows displayed by xpra

Clicking the minimise-window button on any window displayed by xpra does not minimise the window. Instead, the window appears to minimise for a few milliseconds and then returns to its original size. The problem occurs every time.The other window-buttons (maximise, close) work as expected.

Steps to reproduce:
First get xpra to display a window, eg,

xpra start :10 && DISPLAY=:10 xterm & xpra attach :10

Then click on the xterm's minimise-window button.

Software affected: (client and server on the same machine)
No changes were made to the stock configuration of xpra or the operating system. The issue can be reproduced using a fresh install of xpra and the operating system in a virtual machine.

Operating systems affected: Ubuntu 14.04 and 16.04.

Window managers affected:

-> xfwm4 (in the xubuntu-desktop package)
-> compiz (in the gnome-session-flashback package in ubuntu 14.04)
-> I have _not_ tried the 'unity' desktop, because my hardware is too old.

Hardware affected:
The problem occurs not only in a virtual machine (kvm) but also on real hardware (intel core2 with gma x3100 integrated graphics)

FYI: you should be using this form to start child commands:

xpra start :10 --start=xterm

This is fixed in r14708. (applied to v1.0.x branch in r14709) Please close if that works for you.

r14709 works perfectly. Thank you!
