problem in NSDistributedNotificationCenter while terminating app

[Ondrej Florian]

Hi everyone,

I am encountering problem where an app is not terminating
correctly because it is stack waiting for reply from remote connection

From the stacktrace I assume this happens when NSApplication is
being deallocated and NSDistributedNotificationCenter tries to
removeObserver. 

Shouldn't this happen before NSApplication deallocates?
Could this be the problem?

Here is the stacktrace:
