Subject: Fix crash when testing invalid MIDI file.
X-Git-Url: https://main.carlh.net/gitweb/?a=commitdiff_plain;h=43c76ff23b7267ab3d78965d9ad6ce9bcc6a8b4a;p=ardour.git

Fix crash when testing invalid MIDI file.

smf_delete() does not handle NULL pointers. This fixes a crash when
checking if a MIDI source is valid.
