1648	assertion failure 'assert len(self._active_readers) >= self._required_shares' in mutable retrieve	davidsarah	kevan	"Reported by Stuart Card:

This was seen with a 1.9.0 client connected to an LAE storage server using an S3 backend (on the ticket999-S3-backend branch), with 1/1/1 encoding parameters. It seems as though the client shouldn't have reported an error in this way even if it was caused by the server.

The assertion failure, at [source:trunk/src/allmydata/mutable/retrieve.py?annotate=blame&rev=5358#L507 retrieve.py line 507], is in code that changed in 1.9.0, so it might be a regression."	defect	closed	major	1.9.2	code-mutable	1.9.0	fixed	assertion error retrieve mutable regression	stucard zooko
