Yes, very mysterious things happened.  Your function name below
indicates that you used my guide or the relevant parts of the doc where
it was copied.  It seems that the folder translation given there
has(had?) bugs since I also ran into this problem.

You also need to give us the inverse function.  So far I can see nothing
wrong with your function, but, it needs an inverse!  The way I debugged
this for myself is to run the two functions back and forth in the python
shell, trying to find cases in which the results where not correct.

I deduced that from 6.5.2 to 6.5.3 there were some changes to the code
which detects infinite folder creation.  It remains to be seen whether
those new checks are buggy, or whether they are correct and uncovered
bugs in our transfolder functions...

Cheers,
Thomas
