Does installing qt-doc fix the issue?

Nope. Sorry for not mentioning which docs were installed:

$ rpm -qa qt\*doc\* | sort
qt5-qtbase-doc-5.2.1-6.fc20.noarch
qt5-qtdoc-5.2.1-1.fc20.noarch
qt-doc-4.8.5-15.fc20.noarch

When I start Qt Creator and go to Help menu, appear a message: 

The page could not be found!

Did you install qt-creator-doc?

Er, where can I find it?

If you are running F20, it is in updates-testing, see comment 5. If you are running F19, it will land in updates-testing soon, in the meantime the build is here [1]. If you are running rawhide and F21 it should be in the default repo.

I have F20, and the steps on comment #5 doesn't install qt-creator-doc

qt-creator does not depend on qt-creator-doc, so updating qt-creator does not automatically install the latter. So you must install it:

su -c 'yum install --enablerepo=updates-testing qt-creator-doc-3.1.2-2.fc20'

Perfect, it works! Although I believe that qt-creator-doc is essential to solve this bug. Those that want to check if this bug was solved should know that qt-creator-doc must be installed.

Thanks a lot :)

Well actually it is written in the update description, see [1] ;)

I encountered the same problem on 2014-08-16; because of this bug report, I downloaded qt-creator on 08-15 which seems to have fixed problem.

Shouldn't there be a dependency on qt-creator-doc for qt-creator?
It might prevent future reports.

I realize that this is not really optimal, however having dependencies on -doc packages is frowned upon, since they are not strictly required for runtime. Also, it is kind of consistent with how the other qt packages are structured: by installing qt-devel, you don't automatically get qt-doc and hence the corresponding documentation in the qt-creator help browser. You must install it manually.
