Release issue...

We are facing this issue for months (years ?), and I still don't understand why...

One upon a time, we cut a release on one of my favorite projects (Apache MINA, Apache Directory Server, Apache LDAp API, Apache LDAp Studio), and we regularly get a message like :

#mvn release:prepare
...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.1:prepare (default-cli) on project project: Unable to tag SCM
[ERROR] Provider message:
[ERROR] The svn tag command failed.
[ERROR] Command output:
[ERROR] svn: No such revision 1138066

which is simply a nonsense. We have a workaround, it's a mater of running :
svn up
and replay the release command, which will succeed.

However, this is just an annoyance that I would like to see removed from our path.

Does anyone has a clue about what's going on ? I would be grateful (even if I just have an explanation like "it's a referenced bug in SVN").
