[Digikam-users] DK doesn't see some .mp4 files

[John Stumbles]

Digikam is not "seeing" some of my mp4 files.

I have a directory containing 3 .mp4 files (and many .jpgs)

$ lsl pix/2013/20131020/*.mp4
-rw-r--r-- 1 john john 72207409 2013-10-20 13:32 
pix/2013/20131020/20131020_090052_p1000424.mp4
-rw-r--r-- 1 john john 21641164 2013-10-20 13:33 
pix/2013/20131020/20131020_090629_p1000427.mp4
-rw-r--r-- 1 john john 55627950 2013-10-20 13:36 
pix/2013/20131020/20131020_100436_p1000494.mp4

but only the first shows up in DK's album view.

I've tried re-building thumbnails in the album, and closing and 
re-opening DK (so it re-scans the albums).

Is there any way to find out why DK doesn't recognise the other files?
Or better still to make it do so?

Each of the mp4 files is straight, unmodified, off a Lumix TZ30 and 
`file` reports each as "ISO Media, MPEG v4 system, version 2"

System is DK 2.7.0, kde 4.7.4, ubuntu oneiric 3.0.0-32-generic-pae
