ValueError: invalid literal for int() with base 10

[ncsalgado]

Some attachments give the following error:
File "C:\Users\adminns\AppData\Roaming\Python\Python310\site-packages\imbox\messages.py", line 55, in _fetch_email_list yield uid, self._fetch_email(uid)
File "C:\Users\adminns\AppData\Roaming\Python\Python310\site-packages\imbox\messages.py", line 42, in _fetch_email return fetch_email_by_uid(uid=uid,
File "C:\Users\adminns\AppData\Roaming\Python\Python310\site-packages\imbox\parser.py", line 157, in fetch_email_by_uid email_object = parse_email(raw_email, policy=parser_policy)
File "C:\Users\adminns\AppData\Roaming\Python\Python310\site-packages\imbox\parser.py", line 214, in parse_email attachment = parse_attachment(part)
File "C:\Users\adminns\AppData\Roaming\Python\Python310\site-packages\imbox\parser.py", line 124, in parse_attachment filename_parts.insert(int(s_name[1]),value[1:-1] if value.startswith('"') else value) ValueError: invalid literal for int() with base 10:

An example of value of var "param" in line 114 of file "parser" is: "filename*=iso-8859-1''PALLETWAYS_Renova%E7aoISO_0212.docx".
So var "s_name" as value ['filename', ''] and it breaks in line 122 in: ...int(s_name[1]) because s_name[1] is ''....

What I did was test if s_name[1] is '' and encode the file name if necessary, replacing line 122 with:
if s_name[1] != '':
filename_parts.insert(int(s_name[1]),value[1:-1] if value.startswith('"') else value)
elif "''" in value:
encoding, encoded_filename = value.split("''", 1)
filename_parts.insert(0, urllib.parse.unquote(encoded_filename, encoding))
else:
filename_parts.insert(0,value[1:-1] if value.startswith('"') else value)

Don't forget to include urllib.
