IEP does not properly load on Ubuntu 12.10

[GoogleCodeExporter]

What steps will reproduce the problem?
Run IEP or Pyzo on Ubuntu 12.10

What is the expected output? What do you see instead?
Iep starts, showing the splash screen, but flickers and stays unresponsive. It 
has also been reported that it eats memory.

This is a known problem with 12.10 related to scrollbar overlays. See for 
instance http://ubuntuforums.org/archive/index.php/t-2046299.html

To fix this, the variable LIBOVERLAY_SCROLLBAR should be set to '0'.
For instance in iep/__init__.py, put right after the "import os": 
os.environ['LIBOVERLAY_SCROLLBAR'] = '0'

Also, Ubuntu 12.10 has a Mac-like menu bar. It seems that only the window title 
that is initially given is used (it does not show the current file). And as it 
is now, the application icon is also not applied. Putting the loading of icons 
and setting the application icon *before* setting the stylesheet fixes it.

A quick test with a minimal example containing a QPlainTextEdit (for the 
scrollbars) reveals that *any* Qt app will be affected.

For Pyzo this should thus be fixed in the init script of the executabele.

Thomas reports:
Other Qt applications work, and get the global menubar. They don't get the 
overlay scrollbars, but we don't have to do anything special to avoid them. 
I've just tested this including Python 3 applications, and using PySide as well 
as PyQt.

Perhaps the issue is more related to PySide, and a newer version of PySide may 
fix it.
Reopening to look into again before the next release.

(Setting to medium priority, the critical part has been solved now)

Update: with PySide version 1.1.2 the bug still persists, so we still need to 
disable LIBOVERLAY_SCROLLBAR to make IEP stable on Ubuntu 12.10.
