That's a somewhat weird error. It suggests it was unable to set the labels for each 'sub-brik' (sample) in your data, but it's unclear why that would be the case.
What does "SurfDsetInfo /Volumes/KaraData/fSIR/p01/p01.results/WMstats.p01.rh.niml.dset" give you?

Another note: you used "-pad_to_node MAX_INDEX", which does not seem appropriate. With MAX_INDEX it pads up to the last node in the dataset that has data, but it can be the case that there are nodes beyond that (without data).
Indeed, when using MapIcosahedron surfaces with "ld" linear divisions, the number of nodes is (ld*ld)*10+2, and the parameter for -pad_to_node has to be one less than that (=(ld*ld)*10+1) because SUMA uses 0-based indexing. Thus the pad_to_node value has to have a '1' in the rightmost position, unlike the number 130445 which ConvertDset uses.
To find the number of nodes in your surfaces, either compute the number of nodes using the ld value that you used, or open a surface anatomical (.asc) file and find the first line not starting with '#'. It should have two numbers; the first one is the number of nodes. Again, you would have to subtract one from the number of nodes to get the required value for -pad_to_node.

Hope that helps,
Nick
