Hi,
after 10-15 minutes eclipse gets very sluggish and finally freezes.

Java HotSpot(TM) 64-Bit Server VM (build 16.2-b04, mixed mode)
Eclipse Platform Version: 3.5.2

One way to speed things up a little when it comes to reproducing this bug
is to open multiple windows in Eclipse. Make sure Roster View is open, then
use Window->New Window ~10 times. Now keep going on- and offline for a bit,
and voilà, there's your crash.
I think it might be because we never use Image.dispose():
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/graphics/Image.html
Application code must explicitly invoke the Image.dispose() method to
release the operating system resources managed by each instance when those
instances are no longer required.

What appears to be common when this happens is the
de.fu_berlin.inf.dpp.ui.SarosUI.getImage(SarosUI.java:251)
Are we using getting and managing handles responsibly?
