Qt 4.4 on Mac OS X - app crashes with NSInvalidArgumentException

[krzemin]

I'm deploying an application on Mac OS X written in Qt4. Under Qt 4.3.x all works fine, but when I try to use Qt 4.4.3 application crashes:

I've tried both Qt dmg installer and own static Qt compilation with the same result. Any ideas?

hey mate, all i know is that exception is thrown when some invalid argument is passed into a function..prolly sm function in 4.3.x has changed in 4.4.3

[krzemin]

Thanks for your quick response :)

But I have really no idea what argument of what function could be invalid. I have commented out all code from main() except QApplication app(..) and app.exec(). Debuger says that application is interrupted at creating QApplication object. There is no crash when I use QCoreApplication instead of QApplication.

Hey,

there's everything allright with your app. The only problem is with your Info.plist file, and customising LSUIElement property - "Application is agent(UIElement)". The same happens to me when I try to customize it. Regardless of the value (true or false) this setting causes application to crash badly. When these lines are removed from Info.plist file:


<key>LSUIElement</key>
<true/>

my application works, and so does yours (I've checked it :)). Unfortunately, the application icon is then visible in dock, and you also get the unnecessary menu bar, but I guess this is the only way to get things working. I didn't find any solution to this problem so far, and neither did google. Just one trace (http://github.com/soc88/avogadro/commit/08515f7b7af95d4626fc6ddb8077e6280fd865ed) of this issue, where guys gave up...

[ayoy]

I've just checked with Qt 4.5 release candidate, and this setting works! :)

I've compiled app in Qt 4.5.0 stable without applying any changes in this area and all works fine :) No ugly crash and no dock icon is visible. It seems it was bug in Qt 4.4.x.
