Subclipse 'Mark as merged' crashes in Eclipse Juno

Question

When i 'mark as merged' a file in the Team Synchronizing perspective, a popup is shown and it says only this :

An internal error occurred during "mark as merged". java.lang.NullPointerException

And then my changes are in a new file *.tmp and the real file contains the server version.

Have you encountered this and fixed it somehow ?

EDIT : version & stacktrace

Versions:

• Svn 1.7.9
• Eclipse juno
• windows xp
• Subclipse 1.8.19

Stacktrace of the NPE :

This was a bug in Subclipse 1.8.19.

Fixed in the 1.8.20 release. So, if possible, upgrade your Subclipse version to latest which is currently 1.8.22.
