1.- I need the stack trace (Linux) or dump file (Windows): see the
rules !
2.- VAR REGION is in an extremely experimental state, both viewer-side and OpenSim-server side. I cannot guarantee it will always work...
3.- Like explained in the
release notes, teleporting to a VAR REGION that is not connected to the viewer prior to the teleport action is bound to cause crashes (because the server doesn't send the proper region size data: that's apparently a server-side bug, or maybe a protocol flaw). A teleport may also appear to "work", but then you will crash later in the session... You should instead log in into the VAR REGION (again, see the release notes !).
