[BZ#772888] Size of VC console window is reset to invisibly small after restart with maximized meld window

Submitted by Vasily Galkin

Description

Problem: after restarting maximized meld window several times the vc console "disappears".

Steps to reproduce: Launch meld like "bin/meld ." in it own git checkout Maximize meld window Ensure that vc console window is visible (enable it in the menu, then drag the separator to the middle of the window height) Close meld Open meld like "bin/meld ." Close meld again Open meld again like "bin/meld ."

Result: console window is enabled in the menu, but is not visible. Really it present but has near-1-pixel height, so it requires dragging from the bottom of the window to make it visible.

The bug is quite strange, but reproduces both on debian with gtk3.20 and windows with gtk3.18.

Possibly it is related to the fact that I have both meld 3.17 master and meld 3.16 installed and runed, so they share some of gsettings data...

According to dconf-editor the value of vc-console-pane-position is saved correctly but is hugely increased in the moment of starting new meld instance. Also I'm not sure by now that bug doesn't affect meld 3.16, but it looks that it's behaviour has some differences.
