[scribus] Problem with text justification

[Alessandro Levati]

Hello,

I am a new Scribus user and I am trying to learn it.
I am using Scribus 1.3.6 on Fedora 11. I found a problem with text 
justification and I am not sure how to solve it.

My document includes a large text frame, which is less wide than the 
page, so an empty space is left inside the right page margin. Some small 
images and text frames lie in that space, but they are wider, and so 
they straddle the right margin of the main text frame.
In the main text frame, the text is set as justified (in the paragraph 
style).
And this is the problem: the text justification near the small images 
and text frames is incorrect.
I fear that my description is rather confused, so here is an image 
showing the problem: http://web.tiscali.it/oct326/justif-problem.jpeg

In the advanced justification settings I set minimum space width at 80%, 
and glyph extension at 98%-102%. If I set minimum space width at 100% 
and no glyph extension, the problem disappears and the text is justified 
correctly. But I'd rather keep the advanced justification settings as I 
chose. Is there any way to get the correct justification in this situation?

Any help would be appreciated.

Thanks and regards
Alessandro
