Having issues with 'The Binding of Isaac'

At least I think it's a bug...
Items I had equipped the first time it occured:
Halo of Flies
Spelunkers Hat
Rosary
2x Cubes of Meat
BrimstoneSpecial Item:
Bob's Rotten HeadWhen using Bob's Rotten Head, Isaac won't throw it (it recharges though), just keeps holding it above his head, getting stuck. Isaac is not able to do regular attacks (upgraded Cube of Meat DID shoot). Also, cards or pills don't work.
Second time it happend, equipped items I remember:
1UP (Mushroom)
Brother Bobby
Pretty Fly
Spelunkers Hat
1x Cube of Meat
BrimstoneSpecial Item:
Bob's Rotten HeadI highlighted the items that I think are colliding which each other, causing a bug, rendering the game useless (or at least the current play you're doing). The second time it happened to me was when going all out on 'Mom', which is REALLY frustrating

By now, this happened to me two times already.
