+Subject: [PATCH] Fix crash with invalid WAV files (#1163) (#1164)
+
+With specially crafted WAV files having the "id3 " chunk as the
+only valid chunk, when trying to write the tags, the existing
+"id3 " chunk is removed, and then vector::front() is called on
+the now empty chunks vector.
+Now it is checked if the vector is empty to avoid the crash.
