I've been seeing "Unknown Object - Abort Decoding... (0x150a), 1 point" on some
packets.  The devices being monitored don't report any problems.  Looked in
DNP3Spec-V6-Part2-Objects-20080901 and Object Group 21 Variarion 10 is valid. 
Checked wireshark source using svn web access and there are 3 mis-defined
constants.

338 #define AL_OBJ_FCTR_16NF   0x1510   /* 21 10 16-Bit Frozen Counter Without
Flag */

339 #define AL_OBJ_FDCTR_32NF  0x1511   /* 21 11 32-Bit Frozen Delta Counter
Without Flag */

340 #define AL_OBJ_FDCTR_16NF  0x1512   /* 21 12 16-Bit Frozen Delta Counter
Without Flag */

0x1510 should be 0x150a, 0x1511 should be 0x150b, 0x1512 should be 0x150c
