Affects: evolution (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I have a vFolder for a given message filter on which the default vFolder
name is the filter rule itself.

I rename the vFolder and everything works fine but after closing and
running Evolution again I see that the vFolder name hasn't been actually
changed.

For example, if the vFolder is named "my old vfoldername" and I change
it to "new vfolder name", after restarting Evolution, instead of the
latter the vFolder has the original name.
