Description
This is hrev39847.
This seems to be reproduceable: Web+ and a Pe window were tiled together. Then, I quit Pe and app_server crashed. This is from the syslog:

Sorry, forgot to mention my uneducated guess that the issue may have something to do with hrev39871.

Fwiw, I can reproduce here on a fresh gcc4 trunk build with an equally fresh WebPositive trunk build. Pe was installed through installoptionalpackage though.
