To reproduce this: 1) Open enough editors so that the tabs for them all don't fit in the window (i.e the ">>N" appears on the right of the editor tabs) 2) Select the ">>N" button and type in some random characters 3) Press enter Assuming the random chars that you typed aren't the name of an open editor you will get this exception.
I also hit this on Windows XP, with 3.1.1, doing the same thing Josh K. described in comment #1 - !SESSION 2005-10-24 13:26:00.332 ----------------------------------------------- eclipse.buildId=M20050929-0840 java.version=1.5.0_04 java.vendor=Sun Microsystems Inc.

Is this still a problem in 3.3? PW
I can no longer reproduce under 3.3M3..
OK. If it occurs again please open a new bug. PW
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
