Bug Description
I installed the latest ubuntu-image from git version, and the issue can be reproduced through following steps:
$ ubuntu-image --version
ubuntu-image 0.8+17.04ubuntu1
$ more pi3.model
type: model
authority-id: 9anEFsr3zJAqJ3z
series: 16
brand-id: 9anEFsr3zJAqJ3z

missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
$ dmesg|tail -n 2
[82470.253410] EXT4-fs (loop2): mounted filesystem with ordered data mode. Opts: (null)
[82493.633046] EXT4-fs (dm-1): bad geometry: block count 118616 exceeds size of device (118528 blocks)
But if I use the snap version (0.5+mvo13), mounting the second partition is OK.

Looks like the partition table is incorrect.
The partition table of the created image is:
Device Boot Start End Sectors Size Id Type
pi3-test.img1 * 2048 264191 262144 128M c W95 FAT32 (LBA)
pi3-test.img2 264192 1210367 946176 462M 83 Linux
After I re-create the 2nd partition to be like this, I can then mount it:
Device Boot Start End Sectors Size Id Type
pi3-test.img1 * 2048 264191 262144 128M c W95 FAT32 (LBA)
pi3-test.img2 264192 1212171 947980 462.9M 83 Linux
