Hi, since a while I have noticed a very strange behavior in Hudson. After a
commit to subversion it starts building the project, and after completion it
starts to build it again and again ad infinitum. This happens in 1.156 and also
in 1.177

The subversion polling always reports that changes are found, but there are no
changes:

Revision:27534
Revision:28031
(changed from 27992)
Done. Took 0 seconds
Changes found

The build then starts with this message (servername replaced with xxxxx):

The workspace shows that hudson is checking out an old version of
https://xxxxxxxx.xxx/koagent/trunk, it does not use the latest version! This
happens with both "Use update" and without the option (There the workspace is
correctly deleted, and the freshly checked out version is still not the last
version in subversion).
