Re: treeview path/iter to undisplayed model item

["Dave Foster" <dave foster gmail com>]

After further testing, I've concluded it is a strange interaction between
the xmms2 client lib (my application is an xmms2 client) and the glib
mainloop.  I found a workaround in that instead of placing items in the
store directly when xmms2 tells me to, I put it in a queue for an idle
function to pick up later.  That seems to solve it atm.
