'swarm connect' fails on LAN-- "invalid multiaddr" despite valid multiaddr

#### Version information: go-ipfs version 0.4.4

#### Type: Bug

#### Priority: P5

#### Description:
Using go-ipfs 0.4.4 on Windows 8.1 in a LAN network, this command fails:
`ipfs swarm connect /ip4/10.145.24.153/tcp/4001/ipfs/$HASH`
(Pretend $HASH is a valid hash.)
Each time IPFS immediately aborts and gives an `invalid multiaddr` error.
Other variations, like `ipfs swarm connect "/ip4/10.145.24.153/tcp/4001/ipfs/$HASH"` etc. also don't work. I've tried every variation I could think of.
The subnets match and other programs that support LAN works just fine-- everything seems to check out on that end. I double-checked the IP addresses and IPFS hashes, etc...
