The fifth argument to pa_scache_play_item() is a proplist. Simply create
a pa_proplist and inject an entry that sets media.role to something else
(e.g. phone or simply a blank string). That should override the default
media.role stored with the item itself.

I suspect the segv comes from some kind of loop within your module, but
it's hard to say without a backtrace.
