When ST2 shows the open file dialog, and then I close it, the windows borders of the system are lost (the window decorator crashed); but everything's OK if no dialog is shown (luckly there are many in ST2). Even worse, when opening the about box, the entire X server crashs and subsequently, all graphical programs also end. I'm using Ubuntu 10.04.3 and ST2 rev 2111. If I must attach some other system information, just ask what to look for.
