[scribus] Scribus 1.5.5 (Debian/Testing) doesn't export link text to PDFs

[Gary Dale]

I'm having some problems with Scribus Generator but this one looks like 
it is with Scribus itself. I have Generator populate a text box with a 
website name and fill in the PDF annotation as the same text prefixed 
with http://. When I look at the text box and the PDF annotations, they 
seem to be OK - they contain what I expect.

When I export the Scribus document to PDF, the lnks work but the text 
isn't there. I can click on where the text box is and it launches a new 
tab in my browser open at the correct address but there is no text to 
suggest that the expanse of white space is actually a link

I'm pretty sure this isn't a Generator-produced error because I actually 
had to fix the first link (of two) on each page because Generator 
somehow filled both links with the second link's data. Or is there some 
setting I need to turn on in a PDF annotation to get it to display text?
