Description Tal Yacobi CLA 2007-12-18 05:57:25 EST 
Build ID: I20070625-1500

Steps To Reproduce:
I couldn't reproduce the bug myself, but as it is an NPE, I thought you might stand a chance with the log.
1. Opened a text file (one of my project's properties files)
2. pressed the delete button multiple times very quickly
3. received a popup stating that the delete couldn't be performed - with details stating a null pointer exception
4. Pressing the delete again didn't work and opened a popup stating that assert failed...
5. closing eclipse and opening it again solved problem.

Comment 1 Paul Webster CLA 2007-12-18 09:33:12 EST 
Tal, was the '"Delete" did not complete normally...' log message the first error in your error log?

Comment 2 Tal Yacobi CLA 2007-12-18 09:46:20 EST 
Yes.
The log started with the NullPointerException followed by a series of AssertionFailedExceptions
