Partial dives are not supposed to be present. If libdivecomputer detects 
a partial dive, it will ignore that dive and continue downloading the 
other dives. Only at the end of the download, when all other dives have 
been downloaded successfully, it will return the error to the 
application. This is a workaround to make sure you can still download 
the good dives.

See commit b7a6be15ca58cc8f89fbc8fa1a4c840e13d51092 for more info.

These are likely temporary failures. These happen sometimes. Nothing to 
worry about. The internal error recovery will take care of them, and 
automatically retry the failed packet...

...unless you get too many failures for the same packet. Then it turns 
into a fatal error, and the download will abort.

If libdivecomputer returned an error as it should, then I suspect this 
might be a subsurface issue. I have no idea what modalSession is about, 
but my first guess would be some Qt related.

This is the same "Skipping incomplete dive" error. Other than that, the 
download looks fine.
