Playlist column widths forgotten on restart #580
Description
Steps to Reproduce (for bugs)
Quit and re-open Exaile.
This was observed after an upgrade to LM18.3 (based on U16.04) that broke some GStreamer codec plugin dependency for mp3 in the repository-provided version 3.3.2, causing this bug despite all qualities of codec plugins being installed, resulting in me testing the latest version.
Expected Behavior
The playlist columns should be at the same width as they were when the application last ran.
Current Behavior
When Exaile starts after quitting, all columns are at their minimum width (nothing in the column can be read), except for the right-most column, which takes up the rest of the screen width.
Also, sometimes when dragging out the collapsed columns to appropriate widths, as soon as the edge of the last (left-most) column "#" for track number is clicked on, the entire application crashes. This last part has been unreliable - e.g. it happened on the first 2 of 3 times this morning, but I only observed it so far on 4.0.0beta2, currently available as .deb installer via PPA.
There is also slightly different starting visual behaviour - in 4.0.0beta2, all the columns begin collapsed onto the same pixel-width, whereas in 4.0.0rc3, they begin with a few pixels regularly spaced between each column edge.
Environment
Linux Mint 18.3 XFCE 32bit edition
Exaile 4.0.0rc3 from source
GStreamer: 1.8.3
GTK+: 3.18.9
GTK+ theme: Mint-X
Locale: en_GB UTF-8
Mutagen: 1.41.1
PyGObject: 3.20.0
Python: 2.7.12
Peculiarity - I also have Python 3.5 installed, but it seems to be defaulting to 2.7 when running.
I looked at another system already running LM18.3 64bit, and Exaile was not shown in the repository at all. Executing from the github release would not start, probably lacking dependencies.
