asterisk users - Aug 2011 - netsock error? some sip clients crashing!

Hello

I have a weird behaviour with our local GSM (3G) provider -- several
SIP clients crash on the android phone, when switching to 3G network,
and in asterisks logs it looks like this - client registers on server
successfull and then crashesh immediately.

Here's suspicious part of asterisk log:

Looks like port should not be there when calling getaddrinfo? Could
this be the cause of SIp client crash?
