There is a difference between Requires(post): and a plain Requires:. The
first statement guarantees that the cache will be created, the latter
might miss to create it.

Just for completeness (it is stated from the bugreport):

A cronjob which updates content under /usr regularly, sounds like a
really bad idea to me. When the caching would be changed to look for the
icon-cache under /var, it would be fine with me. A quick&dirty (or
well-designed&clean) solutions might be symlinks like
/usr/share/icons/.../.icon-cache ->
/var/cache/icon-cache/usr_share_icons_..._icon-cache and
'gtk-update-icon-cache' writes either directly into this file or reads
the symlink and recreates it.


Else, are you sure that all possible icon-directories can be enumerated
in this way? (thtat's not a critic, I just do not know it ;))
