YAY! Thank you!

And O2 value of 0 is, admittedly, fairly unlikely, wouldn't you say?

No, in this case this is the right place to report it, the Garmin code still
hasn't been merged upstream in libdivecomputer and is only available via our
own branch... so this is a Subsurface thing.

So this is almost certainly a .FIT file on your device that confuses our parser.
Ideally we'd figure out which one it is and have you send us just send that one
file, but that puts the onus on you, if you don't mind sharing the data
privately, you could simply put ALL of the .FIT files under Garmin/Activity on
your Mk2i into a .zip file and send it off list to me and then I can figure
this out here.
Obviously there is a risk that some sort of personal data might be included in
those .FIT files (I seriously don't know exactly what is and isn't included in
those... they contain the wildest stuff...), but I doubt it will be anything
more than information about where you did exercises (and what exercises you
did) and I really don't care about any of those things... but likely this will
help us figure out what causes that annoying error above.
Let me know if you need help how to do this (or if you'd rather figure out
which .FIT file it is and then only send me that... I'm somewhat hopeful that I
could walk you through how to do that as well)
Thanks again for bringing this up!
