Description Martin Oberhuber CLA 2011-07-11 10:42:17 EDT 
Build ID: CDT 8.0 (Indigo)

Not sure what triggered it, but I found this in my .log:

Comment 1 Martin Oberhuber CLA 2011-07-11 10:43:14 EDT 
Preceeded and probably caused by that:

Comment 2 Marc-André Laperle CLA 2011-12-12 00:17:21 EST 
I just got that too with 8.0.1. I was in the History view (EGit) and did a mixed reset. That probably triggered the decoration.
Comment 3 Karsten Thoms CLA 2018-02-13 04:34:43 EST 
Just hit this NPE, using CDT 9.4.0

desc.getDefaultSettingConfiguration() yields null, leading to this NPE:
