Invalid clip format when importing from GoPro camera

I'm desperately trying to add a new clip but kdenlive insists on telling me that the clip is invalid :).

jonathan@ramona:/tmp $ file GOPR2127.MP4
GOPR2127.MP4: ISO Media, MPEG v4 system, 3GPP JVT AVC

Here's the console output of kdenlive:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f9798014f00] decoding for stream 0 failed
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f9798014f00] Could not find codec parameters (Video: h264 (avc1 / 0x31637661), 15073 kb/s)
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f9798014f00] decoding for stream 1 failed

I've been googling for that but nothing popped up. I must be missing something!

Thanks,

jonathan
