Bug#896068: gedit-plugin-git: diff column fails to display

[Marcus O'Flaherty]

Package: gedit-plugin-git
Version: 3.22.0-1
Severity: important

Dear Maintainer,

Using a fresh installation of Debian Stretch XFCE, the diff column of the gedit git plugin does not persistently show.
The diff column on rare occasions appears very briefly, and it's contents are correct, but it disappears almost immediately.
Running gedit from the terminal, no output is produced. Exporting GEDIT_DEBUG_GIT_PLUGIN=1 results in the following:
    
    git/workerthread.py:121 (run) GitStatusThread<Thread-1>: result callback idle started
    git/workerthread.py:145 (__in_idle) GitStatusThread<Thread-1>: result callback idle finished
    
Using:
Gedit 3.22.0-2
gedit-plugins 3.22.0-1
libgit2 0.24.4-1
libpeas 1.0-0
XFCE4 4.12.3
