Autocompletion - AttributeError: 'str' object has no attribute 'is_folder'

[mcepl]

Rope: 0.9.2. Ropevim & Ropemode - taken from http://rope.sourceforge.net/ropevim.html snapshot

In vim, when I activate autocompletion (M-/) with cursor positioned like this (X is cursor)

    grid = CompanyDataGrid()
    grid.X

following stacktrace will occur:

This happens for custom classes (from my project), but not for buildin types (like dict) - eg. this works:

    d = {}
    d.X

Does this happen for the repository version of rope?

I have no clue what to do with this bug, because I cannot reproduce it at all. Please, reopen, if you have something to add.
