After logging in and my avatar is rezzed. I then try reading through all group notifices that have been received whilst i have been offline. After getting through 4 or 5 of them the viewer crashes. I used the three yellow arrow icon to go to the next entry in all cases. This has happened twice with release candidate 1.18.3.3 and at least four times with 1.18.2. I havent spotted any other patterns with the number of notices recieved, or any particular attributes of those notices i'm able to read before it crashes. I have sent dump information for several of these now also.
If i only have one ot two notices I can read those safely without it crashing.
