xulrunner 6.0: No menu bar or focus on Mac OS X

Hello,

I'm trying to update my app to the latest xulrunner 6.0 (I suppose 6.0 
is ment to be the latest version for production use?) on Mac OS X but 
are unable to get a working menu, dock icon, or focus for keyboard input 
with 6.0.

I also tried to create a new minimal app as described on 
https://developer.mozilla.org/en/getting_started_with_xulrunner. I'm 
installing the application bundle via install-app, the window comes up, 
but the menu/keyboard focus won't work on 6.0. Tried the same procedure 
with 2.0 and everything  works as expected.

Is xulrunner 6.0 broken on OS X or am I doing something wrong?

--------

This is the procedure I'm following:

1) Creating the application folder structure (application.ini, 
chrome.manifest,...) in /Users/michael/temp/myapp/

All files are as described on 
https://developer.mozilla.org/en/getting_started_with_xulrunner. Just 
changed the application.ini slightly:

[App]
Vendor=XULTest
Name=MyTestApp
Version=1.0
BuildID=20100901
[email protected]

[Gecko]
MinVersion=6.0
MaxVersion=6.0


2) /Library/Frameworks/XUL.framework/xulrunner-bin --install-app 
/Users/michael/temp/myapp

3) Start app:

a) /Applications/XULTest/MyTestApp.app/Contents/MacOS/xulrunner -jsconsole
-> "Could not find the Mozilla runtime."

b) /Library/Frameworks/XUL.framework/xulrunner-bin 
"/Applications/XULTest/MyTestApp.app/Contents/Resources/application.ini"
-> window comes up, but no keyboard focus, menu or dock icon

c) /Library/Frameworks/XUL.framework/xulrunner-bin 
/Users/michael/temp/myapp/application.ini
-> like (b)


Thanks in advance,
Michael
