Comment 1 Ralf Folkerts CLA 2015-10-22 01:43:58 EDT
Just got this error during a Svn-Team-Sync:

- Sitched to Team Synchronization Perspective
- Choose "CVS Workspace", synchronized, updated all
- Choose "SVN Workspace", synchronized
- got Conflict-Markers on two Projects
- selected "Update all incomming changes"

--> the error occured while the Projects were being updated.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
