Crash with ELF which doesn't containt a .strtab section neither a .symtab

What steps will reproduce the problem?
1. try to instranciate a bintools.elf.ELF objet with a ELF which doesn't 
containt a .strtab section neither a .symtab and you obtain this:
Traceback (most recent call last):
  File "./apply_patch.py", line 81, in <module>
    p_in_elf = ELF(p_in)
  File "/home/cocolapin/python/lib/bintools/elf/__init__.py", line 50, in __init__
    strtab = self.sect_dict['.strtab']
KeyError: '.strtab'

What version of the product are you using? On what operating system?
revision 23
GNU/Linux x86

Please provide any additional information below.
a easy workaround is to modify bintools/elf/__init__.py by
49,51c49,52
<         strtab = self.sect_dict['.strtab']
<         self.strtab = StringTable(self.io, strtab.offset, strtab.size)
<

<         symtab = self.sect_dict['.symtab']
<         count = symtab.size / Symbol.LENGTH
<         self.symbols = self.load_entries(symtab.offset, count, Symbol)
<
