Do they cast spells acquired by their class whilst wearing armor without incurring spell failure chances?
Under weapon and armor proficiency it is not explicitly stated that they do as the Sorcerer and Wizard listings do. Nor is it stated that they don't incur standard arcane spell failure chances like Bard and Magus do.
My initial assessment is that they can cast spells granted by their class in armor they are proficient with and not incur the normal arcane spell failure chances.

Red Mantis Assassin: there is an errata which says
Editor's Note:
In switching the Red Mantis assassin over to casting spells from the sorcerer/wizard spell list rather than keeping a special Red Mantis spell list of her own, we inadvertently left out the line that says that Red Mantis assassins ignore arcane spell failure chances while wearing light armor, just like bards.
Prophet of Kalistrade: they have spell failure chance with armor as a wizard.

Prophet of Kalistrade:
He cast arcane spell so must follow the rule from PRD
Arcane Spell Failure Chance: Armor interferes with the gestures that a spellcaster must make to cast an arcane spell that has a somatic component. Arcane spellcasters face the possibility of arcane spell failure if they're wearing armor. Bards can wear light armor and use shields without incurring any arcane spell failure chance for their bard spells.
Casting an Arcane Spell in Armor: A character who casts an arcane spell while wearing armor must usually make an arcane spell failure check. The number in the Arcane Spell Failure Chance column on Table: Armor and Shields is the percentage chance that the spell fails and is ruined. If the spell lacks a somatic component, however, it can be cast with no chance of arcane spell failure.
Shields: If a character is wearing armor and using a shield, add the two numbers together to get a single arcane spell failure chance.
