Ah, cheers.  I'd looked through the bug list and seen that one, but not realized 
the submodules were using `git://` URLs until just before your email arrived.

Yup.  It's a bit finnicky for me to do that given that the submodules are 
defined by my upstream (I can send them a patch, but it's a PITA to ask them to 
make a patch release just to deal with this issue).

I did look into just downloading a tarball of the source, but that has some 
issues of its own -- since the CMakeLists.txt of the project I'm building 
defines some rules for comparing the version number against the output of `git 
describe`, I run into some rather nasty issues where the git history compared to 
is that of the snap package itself (!).

I'll follow up with my upstream and see what I can do, anyway.  Thanks again for 
the help and advice!
