Build failure: "Cache key missing"
When I run bst build core/epiphany.bst
today, it fails inexplicably with this error:
[--:--:--] START [core/epiphany.bst]: Caching Artifact
[00:00:00] FAILURE [core/epiphany.bst]: Caching Artifact
[00:00:38] FAILURE [core/epiphany.bst]: Cache key missing
I've just now reproduced it three times in a row.
