[Qt-interest] Crash when application launched.

[Manish Chaturvedi]

Hi All,

I am writing a Qt application on Mac using Qt 4.5.3. This application does well when accessibility is not turned on my machine but when I enabled accessibility from Preferences->Universal access-> Enable access for assistive devices, my application started crashing while launching.


Here is the crash log for the same

I don't see this problem when my application is run from Xcode. This crash is observed only when I am installing my application to Application folder. Is something I am missing while creating the installer of my application? Any help will be appreciated!

Thanks in advance!
