Description of Problem:

When selecting Details, there is the button
"Install Theme", as well as "Open Theme directory".

When I have the tab "Window Border" or "Windows
Content" (maybe not correctly translated from
german) selected, the "Open theme directory"
button will point to ~/.themes. This is ok.

When I have "Icons" selected, "Open theme
directory" will point to ~/.icons. This is ok, as
well.

BUT:

The "Install theme" button will always install a
theme to ~/.themes . This is confusing. It should
install an icon theme to ~./icons. (As this will
actually work).

Even, if the button is supposed to always install
t ~/.themes, then "Open themes directory" has to
point to that directory as well, always.

Otherwise one could think the "Open themes
directory" button belongs to the tab currently
selected, while the "Install theme" does not.

This is simply unlogical. UI bug.
