I think you're ELF files are corrupted for some reason. objdump doesn't want to work with them, and readelf prints out a lot of junk when asked to print section information, including that all the section names are "NULL". gem5 was not handling these sorts of problems gracefully (although the ELF files being wrong is the root problem) and I'll have a patch out to improve that hopefully early next week. I expect this particular issue to segfault gem5 as it exists today.
