[Pkg-roundcube-maintainers] Bug#911323: Inline Images not displaying

[bkw+1539883323 at 70mpg.org]

Package: roundcube
Version: 1.2.3+dfsg.1-4+deb9u2

Inline HTML images are not displaying in Roundcube.  In my settings, I 
have "Display remote inline images" set to never.  This causes an email 
with inline images to have areas with a pink box instead of the image.  
If I then click on the button that reads "Display images", next to the 
text "To protect your privacy, remote images are blocked in this 
message", the pink boxes go away, but the images are still not shown.

If I change the setting for "display remote inline images" to "always", 
then emails are shown neither with inline images, nor pink boxes.

Online, it seems like this should be resolved by the setting 
"mime_magic=null", but I already have that setting in 
/etc/roundcube/defaults.inc.php

Ideally, inline images would be shown when clicking on "display images", 
or when the user sets their settings to always show inline images.

I am using Debian GNU/Linux 9.5, kernel 4.9.0-8-amd64 with the Debian 
version of apache2: 2.4.25-3+deb9u5.

Thanks!
