Why has this blockchain transaction not confirmed? ea5ee0a3734356a71b2b39deafb656715bad42fb297497f7f694d4a7a0f6335c

Is due to the fee being low 0.0001? or something else?
It depends on a (currently) unconfirmed input: https://blockchain.info/tx-index/106830375/1

There is also a warning on this input (previous output) that it is a double spend, probably due to the ongoing malleability attack.

Warning! this transaction is a double spend. You should be extremely careful when trusting any transactions to/from this sender
