Crash caused by recent dbus-sharp library change

[Robert Dyer]

Despite my best efforts to ensure the binary is not referencing NDesk.DBus, it seems to somehow be doing just that and crashing!

It appears this only happens when I suspend (or resume, who can tell exactly when) and is replacing my old suspend/resume crash (another open bug).

I definitely did a make clean, make uninstall, remade it, reinstalled it, verified via grep that 'NDesk.DBus' does not occur in *any* file in the build directory or the install path. Ideas?

Got it again, not at resume/suspend time.

@robert: I still havent seen this crash myself. Could you try out this patch?

[Robert Dyer (psybers)]

Again, with the standard Ubuntu versions of ndesk-dbus.

This is not a duplicate (exactly) of bug 678426, but I am marking it as such as I believe that bug makes clear what is happening *here*. This bug definitely happens when performing Gmail updates (as I figured out and forgot to report here). So basically, this crash is related to the NDesk.DBus usage of the libnotify-cil call chain.
