KnitVersionedFile No default access_method or index any more

[Mirko Friedenhagen]

I upgraded bzr to 1.4 using the installer for Python2.5. I already had bzr-svn-0.49 installed and afterwards most bzr commands did not complete.

D:\ws\default\mailservice-loadtest-bzr>bzr missing
Using last location: svn+https://<email address hidden>/svn/somesvnpath
bzr-svn is not up to date with installed bzr version 1.4.
There should be a newer version of bzr-svn available.

I have fixed this by applying the suggestion of bzr-1.4rc1 (API breaks):

The version of bzr-svn you are using is not compatible with Bazaar 1.4, see the second line of output. The 0.4 branch will work with 1.4.

[Mirko Friedenhagen (mfriedenhagen)]

 * Well, then maybe the branch naming is a bit misleading :-):

 * On http://bazaar-vcs.org/BzrForeignBranches/Subversion?highlight=(svn)#branches it states that trunk is bleeding edge, launchpad tells correctly that 0.4 is the current development focus and 0.4.9 tricked me into thinking, it would be newer than 0.4

 Best Regards

 * I now installed http://people.samba.org/bzr/jelmer/bzr-svn/0.4/.
 * The repo is rather big (>200000 revisions). Now if I use 0.4 and execute `bzr pull` it will run immediately to the last revision pulled before and then stop and do nothing forever.
 * Do I have to checkout the project freshly?

0.4.10 works with bazaar >= 1.4
