[Fedora] extremely slow shell starts (trying to debug, dbus related)

[Walter Cazzola]

Hi,
some times ago I'd a similar behavior I didn't dig much in that so I
don't know if dbus was the resposible of the delay in my case but I
found out that the delay was provoked by the loading of a really huge
.history file. Removed that and the options to save it anything worked
smoothly as usual. Maybe this apply to you as well.
