[Pkg-xfce-devel] Bug#869793: gtk3-engines-xfce: Seems to be required for dark themes to work on XFCE in Stretch for some programs

[Erik Brangs]

Package: gtk3-engines-xfce
Version: 3.2.0-2
Severity: minor

Dear Maintainer,

   * What led up to the situation?

I've updated to Debian Stretch from Debian Jessie today. Upon launching some applications (e.g. Thunderbird), I noticed that they didn't properly obey the dark theme that I had installed.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?

I tried a few things, including installing new themes, which didn't have any effect. After installing gtk3-engines-xfce, the theming worked correctly again. When I uninstall the package, the theming is no longer obeyed.

   * What outcome did you expect instead?

I would have expected gtk3-engines-xfce to be installed when upgrading from Jessie to Stretch. If that's not possible, a warning during the release notes or something similar would have been nice.
