Comment 4 for bug 901410

That's what I suspected, unfortunately.

There's no bug tracker for libsmbios, but there is a mailing list. It doesn't appear to have had much activity recently, but you could try reporting the bug there. If the list proves unresponsive there are some email addresses in the libsmbios source we could try. If we can get a fix for libsmbios then we can apply the same fix to dell-laptop. I don't see how we'll be able to fix this without some help from Dell.
