[scribus] Vertical centering of text in a frame

[Ken Springer]

Scribus 1.4.6
Windows 7

I want to center a line of text in a frame.  But so far have not found a 
reliable way to do this.

I didn't find any easily selectable option, but for a couple of frames I 
could "fake it" by using the baseline offset in advanced settings.

But with frames of a lower height, it doesn't work.

I found a script here that claimed to do it, 
http://superuser.com/questions/231576/scribus-vertically-align-text-within-a-text-framed, 
but it doesn't.

Is it even possible in 1.4.6?  What about 1.5.2?  For the current 
project, 1.5.2 is not an option but I would like to know if it can be done.
