I am not able to reproduce the issue. However, PyQt4 and/or Qt5 seem to be a bit 
flaky. On my Mac several menu entries are missing or are shown incomplete whereas 
the same does not happen with PyQt4 and Qt 4.8.5. Please try the later 
combination.

I am using eric5 with the following depandencies:
Checking dependencies
Python Version: 3.3.3
Found PyQt4
Found QScintilla2
Found QtGui
Found QtNetwork
Found QtSql
Found QtSvg
Found QtWebKit
Qt Version: 5.2.0
PyQt Version:  4.10.3
QScintilla Version:  2.8
All dependencies ok.

The current version of eric5 is 5.4.0 RC1. But indeed, the previous version of 5.3.9 
also has the same issue. And I didn't use any previous version before.

My issue is I cannot configure eric5 in the preference for some items, such as editor's 
all items. But some other items can be configured.

The error log is as the following:
