That message is coming from mwrank. For curves with 2-torsion like this is uses a 32-bit data structure to hold some information, which can only handle curves with at most 31 bad primes. Yours has 37.
When I wrote that code most machines were 32-bits so that was a reasonable restriction. A quick look at the code suggests to me that on a 64-bit machine that bound could be doubled. If so, mwrank could handle your curve. I will test that. If it works easily then I will report that here: you could patch your version of eclib (which is built when Sage is built). It would take longer for the patched version of eclib to get into the official Sage distribution.
