 In
 https://github.com/MythTV/mythtv/blob/master/mythtv/bindings/python/MythTV/methodheap.py
 the {{{getSGList()}}} function can return either an integer or a list of
 strings or a tuple of lists of strings.

 How is a caller supposed to be able to deal with that?  A caller will
 typically want to do:

 {{{
     dirs,files,sizes = BE.getSGList(host, sg.groupname, sg.dirname)
 }}}

 But that will cause an exception when the return value is one of the -1,
 or -2 values.  -1 could be quite common for an empty SG for example so
 it's not like it's even limited to error situations strictly.

 I wonder how many other functions have this kind of problem.
