Themes in $HOME not followed by Synaptic Package Mngr

[layingback]

18.04 clean (re-)install.

Create a unique theme (remaking Radiance/Radiance-MATE from 10.10 days) in /usr/share/themes and apply, and it is then followed by all apps that I have tried. As expected.

(Theme was created along similar lines to this: https://ubuntu-mate.community/t/how-to-replace-ubuntu-mates-green/17686)

However, copy/move exactly the same theme in $HOME/.themes - which should work, and try to use it from there, and there is a problem. It appears in the choices OK, and is followed by almost all apps, but Synaptic Package Manager does not load with the new theme at all, but with the Redmond theme - all aspects of it!

The part of the theme causing the issue appears to be the Controls part of the Customize theme in Appearance Preferences. If that is changed via Customize... to Radiant-MATE, Synaptic Package Manager will display with the new theme as desired. Change it back to the new one in $HOME and SPM switches to Redmond again.

I suspect that Synaptic package Manager is only finding the Controls part of the theme if it is physically stored in the File System (vs $HOME). Presume Redmond theme is presumably used as the next available after 'Radiance'.

Low priority issue, but annoying as theme is not preserved over re-install if in File System rather than $HOME.

My understanding is that Synaptic is running as root, not as your user, so it only has access to system-wide themes, not themes only in your user directory.
