BEEM - Android XMPP

I'm using the otr branch.

Steps to reproduce:
- Log in with beem.
- Leave it in the background.
- Receive a casual call.
- Experience how you have to kill beem several times and it becomes kind of unstable for some reason from that moment on.

I'm using Android 2.3.3 CyanogenMod on a Nexus One.

Here's what I've got with logcat:
// Some never useful android output here
...
D/ConnectivityService( 162): ConnectivityService::handleDisconnect() - disconnecting netType(0)
D/ConnectivityService( 162): ConnectivityService::handleDisconnect() - netType(0) reason: 2GVoiceCallStarted
D/ConnectivityService( 162): ConnectivityService::handleDisconnect() - netType(0) extra info: internet.ctimovil.com.ar
D/ConnectivityService( 162): ConnectivityService::handleDisconnect() - netType(0) attempting failover
D/ConnectivityService( 162): ConnectivityService::tryFailover() - checkType[1 is default, network pref = 1
...
// Some more not so useful output here
...
// And then when I try to open Beem again, I get this:

Beem from this point on for a while gets really hard to use, it kind of freezes when connecting, and I've experienced sometimes the whole phone being freezed when I try to unblock it, but I can't be sure if this is Beem's fault.
