Error received from smart server

[dobey]

Using bzr 1.14rc2 on Jaunty, I got the following trying to merge a branch for review:

bzr: ERROR: bzrlib.errors.ErrorFromSmartServer: Error received from smart server: ('error', "'AbsentContentFactory' object has no attribute 'get_bytes_as'")

Is the branch you are merging from a stacked branch? If so, was that branch ever pushed to with bzr 1.14rc1 or older?

If both of those are true, this is bug #354036. See that bug for some workarounds (and detailed analysis if you're curious).
