Z-push problem with android 4.0 on kolab 2.3.4

[Alexander Haensch]

I investigated the problem a little bit and it seems that some initial
handshake is not good for android 4.0.x. In Android logcat it shows
repeatedly:

E/__eas[email at address.com](10575): Uncaught exception in
EasSyncServicejava.lang.NullPointerException
W/Email   (10575): Account email at address.com has inconsistent mailbox
data; fixing up...


So i think android 4 is not understanding the z-push message.
What can we do?
