But here is one user who I think describes the quality of this feature quite well:
So I used the Mercurial support in NetBeans 6.1 (as I have been for some
time), and something went wrong. NetBeans 6.1 did not crash, but recovered and saved the java exception for me, I viewed the exception stacktrace and it was obvious it was a crash inside the NetBeans 6.1 Mercurial support code. There was an option of reporting the crash so I hit the "Report" button to report the problem, then continued on with my work.
Then a few minutes later, I noticed that I had a Firefox tab open to a netbeans site... It said:

The NetBeans development team!
It automatically detected a matching java exception in a previously filed bug report, detecting the duplicate bug report.
So NetBeans 6 did everything right as far as I'm concerned:
1. The tool did not crash or stop or even have to restart due to the error
2. It allowed me the option of reporting the problem
3. It made it trivial to report the problem
4. It automatically submitted the report and data seemlessly and easily
5. It detected it was a duplicate and let me know it was.
Good work guys.
