I get this crash when attempting to close window without any stress tests or another unusual things.

Doesn't reproduce for me, on hrev56792. I let the application run for a while and started and stopped StyledEdit and others while it was running. No crash.

Seems to be some race condition so it may be timing dependent. Also using SMP may help reproducing.

The VM I tested in had 2 cores allotted.

Reproducible on metal, i7 8 cores.

I hit this app_server crash today on hrev58228, 64 bits. With only a couple of Tracker windows open. Moved a folder around, closed a window. Puff.

On a slow Atom N2600 (2C/4T) netbook, using framebuffer, if that changes anything.
