I just had a look at this and am capable of reproducing it (on Plone 
3.1.1) -- but also with filestorage! So it doesn't really look like a 
RelStorage issue to me.

Are you sure you are using the same Plone and CMFEditions versions when 
you are comparing the storages?

The reason for this error is that 
Products.CMFEditions.ZVCStorageTool,_encodeMetadata expects "comment" to 
be a string, but with the newest Plone it gets an unicode object.

Probably due to changes in CMFEdtions skinscript "revertversion.py".
