Macdive uses libdivecomputer for downloading, but not for parsing. This is 
mainly because in the early days, the libdivecomputer parsing support wasn't 
really ready yet. Normally we are in perfect sync, but sometimes a small 
difference like this pops up. I'll check with Nick.

Could you send me a memory dump of your device? That will help to investigate 
and fix the problem. Just run the pre-build binary and send me the generated 
dump and logfile.
