Yes, it is.  If you look at it with mkvinfo GUI you'll see that there 
are no keyframes there.

You can fix it using yamkaRemux, make sure to pass the -fixKeyFlag 
option.  With this option yamkaRemux parses H.264 tracks and looks for 
IDR nal_init_type.  It uses that to fix the Matroska SimpleBlock 
keyframe flag.

You can get yamka source here:

Binaries here:

Hope this helps,
