> I have not verified/reproduced this yet. This bug reported on stack overflow:

> If saving an initial flow version fails, a flow can be created with no versioned flow snapshots. (The flow has {{"versionCount": 0}}). Such a flow can be created by saving a flow snapshot that changes the flow name from the already versioned flow, according to the reporter on github. The original reporter was usingthe git flow persistence provider and the nipyapi {{versioning.save_flow_ver()}} call.
> When tying to delete this flow using {{DELETE /buckets/<bucketId>/flows/<flowId>}}, it fails with a 409 error.
> The workaround is to save a dummy flow snapshot to get the flow to version 1 and then the entire flow can be deleted.
> The fix is that such flows (flows without versions) should be deletable.
