Hardcoded path for SSL Certificates file

[Thomas Vander Stichele]

After patching for python < 2.6.3, I now get this traceback when starting the applet:

[thomas@otto ~]$ ubuntuone-client-applet
Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/dbus/connection.py", line 586, in msg_reply_handler
    reply_handler(*message.get_args_list(**get_args_opts))

    parameters['oauth_token'] = token.key
AttributeError: 'NoneType' object has no attribute 'key'

At the same time, I got an error dialog that popped up (attached)

That was non-obvious to figure out, but it seems like the culprit is this missing file:

/etc/ssl/certs/ca-certificates.crt

This does not exist on my fedora system. Before using it in ssl, at the very least its presence should be checked so a nicer error can be generated.

[Thomas Vander Stichele (thomasvs)]

Attaching a patch that does just so.

Now to figure out where I should be getting this file from in the first place.

[Thomas Vander Stichele (thomasvs)]

A better patch that also takes into account the path that Fedora uses.

This might be reworked at your discretion of course.

It appears openSUSE does this differently as well. They don't seem to have a ca-certificates.crt file at all. I wonder how people do SSL cert validation in Python on SUSE.
