Summary: problems using the shelve module

Details: I'm running Python 1.5.2 (#4, Jan 12 2000, 22:14:11)  [GCC 2.95
19990728 (release)] on irix646. 

While using the shelve module the following error message occurs:

>>> import shelve
>>> class someClass:
...   def __init__(self):
...     self = [13, 17]
... 
>>> object = someClass()
>>> dbase = shelve.open('testshelve')
>>> dbase['key'] = object
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python1.5/shelve.py", line 71, in __setitem__
    self.dict[key] = f.getvalue()
  File "/usr/local/lib/python1.5/dumbdbm.py", line 111, in __setitem__
    (pos, siz) = self._addval(val)
  File "/usr/local/lib/python1.5/dumbdbm.py", line 87, in _addval
    f.write('\0'*(npos-pos))
TypeError: can't multiply sequence with non-int

Comment:
This is fixed in 2.0.  If you want to fix it yourself in 1.5.2, change 	the
line "pos = f.tell()" to "	pos = int(f.tell())" in method _addval() in
dumdbm.py.
