[web2py] weird slash problem

[rāma]

Traceback (most recent call last):
  File "C:\web2py\gluon\restricted.py", line 188, in restricted

TypeError: 'str' object does not support item assignment

Posting this because it started affecting my appplication functions as
well. More info: Some of my view's "edit controller" link has this
weird slashing problem thus the error in "invalid request" appears.

Platform: Windows.
