Null files

[quatermass]

On creating a new play-list I found the Android App had added some album titles with 'null' as the name with zero length.

I think this happened because when I selected a single song in the root of my music list to add to a queue, it came up with "Added 39 songs to queue".

I think it added album names which would explain all the null names I've got in my playlist.

Now it will not save my playlist...

Using Windows 7 Pro:
Subsonic version 4.3 (build 2087) – January 7, 2011
Latest Android App. on HTC Desire HD (v2.2)

Is this an Android or Server bug?
