Recently I moved from Debian to Mac OS X (Yosemite), and after starting my application getting error in terminal while running:
relrin at MacBook-Relrin in ~/code/Helenae/Helenae/helenae/gui on git:dev+? workon code
=> run_wx.sh CloudStorage.py
Traceback (most recent call last):
File "/Users/savicvalera/code/Helenae/Helenae/helenae/gui/widgets/Filemanager.py", line 286, in OnSize
self.sb.SetStatusText(os.getcwd())
File "/Users/savicvalera/code/Helenae/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/_core.py", line 16711, in __getattr__
raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the StatusBar object has been deleted, attribute access no longer allowed.
However in Debian this application didn't say about any errors. How can I fix this issue?

You can capture the error in a try exception block with a wx.PyDeadObjectError exception.
You can also remove the hasattr by using a AttributeError exception.
