These two things are not the same. In Gramps, your locale has been set, and str has been redefined so unicode is used. In python in terminal, these are all the ascii codec.

As you want to pass a path, you should probably pass the path in the encoding of the filesystem.
So something like

        fname = self._filename.encode(sys.getfilesystemencoding())
You should check if ROOT_DIR you use is already unicode. I know HOME_DIR in const is, so encode works, but for ROOT_DIR I see

 ROOT_DIR = os.path.abspath(os.path.join(os.path.dirname(
        unicode(__file__, sys.getfilesystemencoding())), os.pardir))

So, there is a unicode cast in there, which I assume will make it unicode in the end.

Hi,

I have a strange problem and don't know if I am alone :

If I do :
$ python
 >>>import cairo
 >>>path = "/home/serge/trunk/src/images/48x48/gramps-geo-mainmap.png"
 >>>cairo.ImageSurface.create_from_png(path)
<cairo.ImageSurface object at 0x7fdbe2207af0>

so, it works.

In gramps in geography.py, I do :
self.geo_mainmap = cairo.ImageSurface.create_from_png(
             os.path.join(ROOT_DIR, "images", "48x48",
                          ('gramps-geo-mainmap' + '.png' )))
which is the same. I split the above instruction like the sample test in python
I always get a SIGSEGV !
with gdb, I obtain :
Program received signal SIGSEGV, Segmentation fault.
