7z2Hashcat + -m 11600 issues

[bowser]

Hey folks, a friend has asked me to crack a small (33kb) 7z file he's forgotten the password to. I've used 7z2Hashcat to extract the following:

Position 1: $7z
Position 2: $2
Position 3: $19
Position 4: $0
Position 5: $
Position 6: $8
Position 7: $ad4cd6f5cbb39e780000000000000000
Position 8: $approx 61000 digits....
Position 9: $29304
Position 10: $09

When running it through hashcat, it fails with a 'no hashes loaded' and when trying Hashcat Beta (5.1) it starts to run but then fails with a segmentation error. 

I can tell than there is LZMA2 compression from the $2 at position 2, but i'm unclear how to make that matter....

The actual hash at position 8 seems faaaar too long to be correct also. 

Any ideas?

Thanks all.
