Bug 351666

Description Christian Halstrick 2011-07-11 01:53:26 EDT

When I want to see the details for a certain change in gerrit by doubleclicking
on that change in the task list an error dialog "Unexpected error while communicating with gerrit" pops up. For other changes on the same gerrit everything is ok. The change producing the bug is change I01c73257 on http://egit.eclipse.org/r.
I am running Mylyn Reviews (Incubation)	0.8.0.v20110608-1400 in an Indigo eclipse.
The error log contains the following:

org.eclipse.mylyn.reviews.feature.feature.group	Eclipse Mylyn
