[Bluez-devel] bluez-gnome and OBEX DBus names

Hello everyone,

I'm running bluez-gnome 0.26 and obex-data-server 0.3 from Gentoo. My
Bluetooth setup is running fine, with the exception of OBEX reception.
When I start the bluetooth-applet from a shell, I get the warning
"Bluetooth OBEX start failed: Invalid path". A bit of dbus-monitoring
shows that this error comes from the OBEX server:

method call sender=:1.96 -> dest=org.openobex
path=/org/openobex/server1; interface=org.openobex.Server; member=Start
   string ""
   boolean true
   boolean true

error sender=:1.94 -> dest=:1.96
error_name=org.openobex.Error.InvalidArguments reply_serial=16
   string "Invalid path"

A look in ods-server.c shows that it's testing for the first parameter
of the method call to be an existing directory, but the bluetooth-applet
is passing an empty string.. and this is because the applet uses
g_get_user_special_dir(G_USER_DIRECTORY_PUBLIC_SHARE) and
g_get_user_special_dir(G_USER_DIRECTORY_DOWNLOAD) to retrieve the
directory names.

So, I now have one suggestion - see the attached patch, two small error
checks to make debugging this _much_ easier - and one question:

how is the average user (yes, there are such things now ;-) expected to
know how to set these *!$%& directories? I needed 20 minutes of glib
source diving to find the relevant code - why doesn't Gnome, e.g., set
this automatically?

Thanks, Yours, Florian
