Disabling theme cache in /etc/horde/conf.php "fix" the problem.
Re-enabling the cache leave horde un-themed again.
BTW While I was investigating I noticed that /usr/share/horde/themes is
not a symlink to /etc/horde/themes-enabled.d rather it is a normal
directory.
Looking at the patch in the bug report that doesn't seem to be the
expected result.
Something probably went wrong in this step
rmdir $(DESTDIR)/usr/share/horde/themes/
so that the symlink couldn't be created.
Somehow fixed this way:
* delete /usr/share/horde/themes/
* actually make a symlink from /etc/horde/themes-enabled.d to
/usr/share/horde/themes/
* change expiration time of theme cache in /etc/horde/horde/conf.php to
few seconds
* refresh
* change expiration time of theme cache in /etc/horde/horde/conf.php
back to longer time
I think to remember that original content of /usr/share/horde/themes/
seems to be missing some files/dir compared to what I've found in
/etc/horde/themes-enabled.d
Unfortunately once I thought the problem was solved I deleted the
original /usr/share/horde/themes/ and I can't be sure I remember right
and I can't check what was actually missing.
