dell-launcher segfault on startup

[Filippo Argiolas]

I needed some updated library for development so I installed from source gnome-desktop-2.25.1.1 and the needed dependencies (glib-2.18.2 and gtk+-2.14.2). I also installed clutter-0.8 from source but I don't think it's related since as far as I can tell clutter-0.6 and 0.8 can coexist nicely.
Anyway now every time I start dell-launcher it doesn display anything and segfaults.
Here is the stacktrace, it lacks some symbol but I still didn't find which.. it seems similar to the one in https://bugs.launchpad.net/netbook-remix-launcher/+bug/240421

For completeness, ume-launcher still works fine.

The Dell launcher has not been updated to work with Clutter 0.8 whereas the UNR launcher has.
Assigning to Neil for more information.

[Nicola Ferralis (feranick)]

I cannot reproduce this bug with a stock version of hardy for the mini.

Should this be marked invalid?

I'm not sure why this bug was assigned to Niel since it is clearly an
environment that has been made invalid by the user. However, we do need
the dell interface to support clutter .8 so we will keep it valid.
