Description of problem:

The Processing plugin of QGIS 2.14 requires the PyQt4-webkit package installed in order to work, however PyQt4-webkit is not marked as a dependency for QGIS by DNF. Perhaps it is not because it is a plugin and not part of the core software, however it is a plugin that is installed and turned on by default and in this end-user's perspective definitely should be considered a necessary component of a full QGIS install.

See the bug listing on the QGIS forum:
https://hub.qgis.org/issues/15237

Version-Release number of selected component (if applicable):
QGIS 2.14.3-3

How reproducible:
100% on my machine

Steps to Reproduce:
1. dnf install qgis
2. attempt to open an instance of qgis

Actual results:

A window with an error message pops up before the QGIS instance is open that says:

Couldn't load plugin 'processing' 

ImportError: cannot import name QtWebKit

Python version: 2.7.11 (default, Jun 21 2016, 09:15:12) [GCC 6.1.1 20160510 (Red Hat 6.1.1-2)] 
QGIS version: 2.14.3-Essen Essen, exported 

The window can be close and QGIS can be used but without the functionality of the processing plugin

Expected results:

A functioning instance of QGIS with access to the processing plugin and no error message.

Additional info:

Problem was fixed by:

dnf install PyQt4-webkit

and opening QGIS again.
