[maemo-developers] profile functions ran on emulator does not ran on device!

[From: daniel wilms]

Hi,

It sounds that you are running the program on device as root? That won't 
work. If so, try to run it as "user" and see if it works. You could as 
well always use the DBus-service (on device) directly to test, like:

dbus-send --session --type=method_call --dest="com.nokia.profiled" 
--print-reply /com/nokia/profiled com.nokia.profiled.get_profile

You can now find as well further documentation about the profile daemon 
[1], the DBus-service [2] and the library [3] in the API references.

1. http://maemo.org/api_refs/5.0/5.0-final/libprofile/index.html
2. http://maemo.org/api_refs/5.0/5.0-final/libprofile/profile__dbus_8h.html
3. http://maemo.org/api_refs/5.0/5.0-final/libprofile/libprofile_8h.html

Cheers Daniel
