[GRASS-user] Interpreting r.watershed accumulation map

[Sören Gebbert]

Hi,
i don't know why this happens. It may be a bug in the temporal framework or
in itzi. Testing the code in the temporal framework seems to work, but more
testing is needed.
However, the traceback is fine, but there must be an error message that
will tell you what mapset is missing and what mapsets are in the temporal
framework search path.

Something like:
"""
You have no permission to "
       "access mapset <%(mapset)s>, or "
       "mapset <%(mapset)s> has no temporal database. "
       "Accessable mapsets are: <%(mapsets)s>

"""

Best regards
Soeren
