Attacked in Markarth, Skyrim

the-elder-scrolls-v-skyrim

When I enter Markarth Keep and get to the first set of stairs towards the King all the guards become hostile and start attacking me. Nothing happens until I reach this point, not even if I drag my weapon. As soon as I reach the stairs they attack me, with or without my weapon drawn.
I only have an 5 gold bounty, and I haven't threatened anybody.
What's wrong? Have anybody else experienced this?

Try committing a minor crime in the city(not the keep) so a guard approaches you in the usual manner. Pay off your bounty or go to jail either way your bounty should reset to zero, preventing this from occurring.
