Can confirm this.
Rendering material icon preview images fail and it seems to be tied to using Tangent Space Normal Map (if I disconnect the normal map node alltogether or change it to anything else than Tangent Space I get no crash)

hitting assert here
BLI_assert(CustomData_number_of_layers(&rdata->cd.output.ldata, CD_TANGENT) == rdata->cd.layers.tangent_len);

Also this doesnt seem to be an issue if you dont specifically assign a UV map in the Normal Map node (if you leave the field blank)

@ideasman42: since you were active here (df70e3de63, 429f6bee28 -- although I'm not sure those commits have anything to with it): mind having a look?
