See, you should have mentioned that before. What you should also
mention is:

1) the _exact_ text of the traceback. Saying "I get an AttributeError"
   is not nearly enough: the full message has info that
   people-in-the-know know how to interpret. Copy-and-paste it.

2) the smallest (or so) of *working* code that will exhibit the error.
   The snippet in your original post doesn't work. Again, copy-and-paste.

Basically, put enough info in your question that we don't have to read
your mind.

Now I'll put my mind-reading cap on...

- Are you sure that tekst_in() is a method, not a function? The
  indentation suggests function, while the self parameter suggests method.

- Are you positive self.tekst is a Tkinter.Text()? Throw in some
  print statements to check. 'print repr(self)' is a good one.

- tekst_tag[tag] shouldn't be the problem (as suggested by your
  original post), as that would raise a KeyError, not an AttributeError.

  etc.

(I'll bet once you've done what I've suggested, you'll have found the bug...)
