Description of problem:
In RHEL/CentOS 7, unlike in RHEL/CentOS 6, certain files in widget-plugins are explicitly removed from official PyQt4 package.

*** excerpt from official PyQt4.spec ***

# qscintilla
%if ! 0%{?qscintilla}
  rm -rf %{buildroot}%{python3_sitearch}/PyQt4/uic/widget-plugins/qscintilla* \
         %{buildroot}%{python_sitearch}/PyQt4/uic/widget-plugins/qscintilla*
%endif

# webkit
%if ! 0%{?webkit}
  rm -rf %{buildroot}%{python3_sitearch}/PyQt4/uic/widget-plugins/qtwebkit* \
         %{buildroot}%{python_sitearch}/PyQt4/uic/widget-plugins/qtwebkit*
%endif

*** end of excerpt ***

Files like qscintilla.py in widget-plugins should be added back when installing qscintilla-python -- otherwise pyuic4 will generate code with broken import while processing .ui files that use Qsci.

As other widget-plugins are placed in official PyQt4 package, I would personally suggest following changes:
1. Put qscintilla.py into qscintilla-python package
2. Make qscintilla-python-devel requires qscintilla-python


Version-Release number of selected component (if applicable):
2.4-1


How reproducible:
Always


Steps to Reproduce:
1. Install PyQt4, PyQt4-devel, qscintilla-python, qscintilla-python-devel
2. cd /tmp
3. wget https://github.com/qgis/QGIS/raw/release-2_8/python/console/console_compile_apis.ui
4. pyuic4 console_compile_apis.ui --output=ui_console_compile_apis.py
6. pyuic4 --debug --preview console_compile_apis.ui


Actual results:
Program exits with error.

ImportError: No module named Qsci.qsciscintilla


Expected results:
A window should open without error.
If everything works correctly, generated Python code (ui_console_compile_apis.py) should end with "from PyQt4 import Qsci" instead of "from Qsci.qsciscintilla import QsciScintilla".


Additional info:
Same problem exists in package "PyQt4-webkit".
