osx - Packaged python .app file crashing, but packaged python .sh file working fine -

i've produced app using python 3.4.3, pyqt4 , other extras (poppler being among them) on os x yosemite.

i'm using cx_freeze produce working .app file , eventually, working msi file. i've been testing app works after building using build command in "python3 setup.py build". works fine, no unexpected crashes. moved on packaging using "python3 setup.py bdist_dmg". opened dmg file/app file, crash instantly giving error:

there's load more i'm not sure how relevant. here setup.py file:

from cx_freeze import setup, executable import sys import os  base = none if sys.platform == "win32":     base = "win32gui"  zips = ["implementation/primaries/gui/designer_files",          "implementation/primaries/gui/themes",     "implementation/primaries/gui/images",      "implementation/primaries/scripts"] build_exe_options = {"packages": ["os"], "excludes": ["tkinter"],                  "include_files":zips}   setup(     name='fyp',     version='0.1',     packages=['implementation', 'implementation.primaries',     'implementation.primaries.gui', 'implementation.primaries.scripts',               'implementation.primaries.gui.pyqt_plugins',     'implementation.primaries.drawing',     'implementation.primaries.drawing.classes',           'implementation.primaries.drawing.classes.tree_cls',     'implementation.primaries.extractmetadata',               'implementation.primaries.extractmetadata.classes',     'implementation.primaries.importonlinedbs','implementation.primaries.importonlinedbs.classes'],     description='muselib',     options = {"build_exe": build_exe_options},     executables = [executable("implementation/main.py", base=base)] ) 

not sure problem is, saw few other people having similar problems seem on either older versions of python or older versions of os x, , fixes didn't solve problem. suggestions how proceed appreciated.

found better way debug this: right click on app file, "view package contents", macos > select executable same name file given in setup.py (for me main). error got: qwidget: must construct qapplication before qpaintdevice

i fixed initialising application object, initialising main window object, showing main window, , calling load method set window. doing part inside constructor reason giving problems. i'm having issues opening/closing windows , opening others on close, that's best question or session of googling.
