Description Chandra Sukiman CLA 2011-07-06 00:39:35 EDT 
Build Identifier: I20110613-1736

When upgrading to Mylyn 3.6 on Eclipse Indigo, I could no longer view my bug details from eclipse. The Task list view is populated, however when clicking a bug item, the screen is displayed as blank. There are some workspace exception thrown which is attached below.

Reproducible: Always

Steps to Reproduce:
1. Install STS 3.7 (based on Indigo)
2. Connect to Bugzilla server and create a query
3. Wait until the bug list is populated 
4. Open any bug and it will display blank screen

I realized that this bug only occurs for bug that is not assigned to myself.
I still can open bugs is assigned to me, however I cannot view others

Do you have any errors in the error log (Window > Show View > Others > Error Log)?
Comment 6 Chandra Sukiman CLA 2011-07-14 22:09:33 EDT 
Yes, please check the two attached files (exception1.txt) and (exception2.txt) for the error. I copied the error from the Error Log view.
