RE: Linux build (1999-05-11-08m6) steps: 1. Run apprunner 2. Open Messenger from Tasks menu 3. CLick on New Msg to open the compose window 4. Compose a message and click Send. Message send, no problem 5. Close compose window. 6. Click on New Msg to open the compose window again. 7. Compose a message and click on Send. 8. Wait for a few second, crash occurs here. Consistently reproducible.
