unable to close dialog after delete of item while playlist is active

[anonymous]

I finished playing a playlist and was given the option to delete a recording. I chose Yes and one program was deleted. I was left with another delete dialog, and could not close the dialog by choosing "no" or typing <esc>. I did not try either of the "yes" options.

(In [8687]) Don't prompt the user to ask if they want to delete a recording if we're inside a playlist. Should fix #1090.
