I have small Python3 application for manipulating some specific XML files. For gui I am using PySide and for parsing files -lxml. 
I had some troubles with freezing it with cx_freeze but finally succeed. Now - some parts of application simply don't work... no error message & no log created. 
For example on Enter press signal in LineEdit - new dialog should be shown... but nothing happens. 
I have same version in standard python files and those are running correctly.  How do I debug the frozen application?
Take a look at the pyside documentation and see if there is a redirect output to a window option - it is entirely possible that something is causing an error that is being printed out to nowhere.
