Description of problem:
The <programlisting>tag doesn't split at page breaks if it is contained in an <example>, it moves onto the next page (same behaviour as an image) if the content is less than one page.  If the programlisting content is more than one page it runs off the bottom of the first page and disappears.

Version-Release number of selected component (if applicable):
0.42

How reproducible:
everytime

Steps to Reproduce:
1.  add a <example><programlisting>...</programlisting></example> near the bottom of the page so you would expect it to run onto the next page
2. build the pdf

Actual results:
Whole content is displayed on the 2nd page.

Expected results:
The content is split over the two pages.

Steps to Reproduce:
1.  add a <example><programlisting>...</programlisting></example> near the bottom of the page so you would expect it to run onto the next page and the one after
2. build the pdf

Actual results:
The content runs off the bottom of the first page.

Expected results:
The content is split over the multiple pages.

Additional info: 
I've only seen this with <programlisting> but suspect it would also do it with other content.
