Octave-3.8.2 problems with gui documentation tab

[Terry Duell]

Hello All,
I'm not sure if I have a local problem or am seeing a bug. I have snooped  
through the bug list but may have missed it.
I have built octave-3.8.2 on Fedora 20 x86_64, by rebuilding  
octave-3.8.2-4.el7.src.rpm in mock using rpmbuild.
If I select the documentation tab in the gui it displays all the section  
headings but none are selectable and the whole gui locks up, and a forced  
quit is required.
Any other Fedora 20 users, or others, seen this behaviour, or can advise  
if it is a known bug?

Cheers,
