I don't. But whatever is inside your dmi, dmidecode must not crash.
Which version of python-dmidecode do you have installed?
Would you open a bug against it?

I believe that its maintainers would appriace a simple reproducer, that
does not involve ovirt or Vdsm. See if you can simplify the code in

def __leafDict(d):
    ret = {}
    for k, v in d.iteritems():
        if isinstance(v, dict):
            ret[k] = v
    return ret

def getAllDmidecodeInfo():
    import dmidecode

    myLeafDict = {}
    for k in ('system', 'bios', 'cache', 'processor', 'chassis', 'memory'):
        myLeafDict[k] = __leafDict(getattr(dmidecode, k)())
    return myLeafDict
