Bug#676190: grass-gui: gcpmanager fails to list source mapsets if non-ascii characters in grass data dir path

[Torsti Schulz]

Package: grass-gui
Version: 6.4.2-1
Severity: normal

Hi,

Using the wxpython GUI Georectify tool is impossible if the path to the grass
data directory (e.g. GRASSDATA) contains non ascii characters (e.g.
'/home/user/Työpöytä/GRASSDATA'). Selecting the source location works, but
the 'Select source mapset:' dropdown menu remains greyed out. The command
console shows the following error message, after selecting the source location:

***
Traceback (most recent call last):
  File
"/usr/lib/grass64/etc/wxpython/gui_modules/gcpmanager.py",
line 377, in OnLocation

tmplist = os.listdir(os.path.join(self.grassdatabase,
self.xylocation))
  File "/usr/lib/python2.7/posixpath.py", line 71, in join

path += '/' + b
UnicodeDecodeError
:
'ascii' codec can't decode byte 0xc3 in position 15: ordinal
not in range(128)
***

Changing the grass data directory path to only contain ascii characters (e.g.
'/home/user/GRASSDATA') makes the Georectify tool usable. This seems to an
issue with how the python code handles path names and unicode characters.

Cheers,
Torsti
