 This one doesn't seem to "fix" the problem, but only ignore it.

 This one could maybe work as a temporary workaround. However this requires
 fuse to be installed on the build machine, and I'm not sure if different
 distributions have different fuse versions/setup that could make things
 more complicate.

 This sounds like the best way to fix it. However I have not even been able
 to find their source code repository so far. Do you know if they have one?
