Unable to set log scale on y axis

Hi all:
I am running Root 5.10.00e on SLC3 IA32 GCC323 which is what I get when working with Athena at BNL. I have created a multigraph with two tgrapherrors on it. The multigraph is drawn ok on linear scale, but if i do c1->SetLogy() I get this error:

log scale requested with zero or negative argument

Which makes no sense to me since none of the Y coordinates of the grapherrors (nor their errors) are zero or negative. Of course, the graph is wrong.

I tried using root 5.16 but got the same results. Am I missing something here?

Thanks,
