When looking at small shellcode dumped from memory, IDA would raise an exception text box:
Traceback (most recent call last):
File "/Users/XXXXXXX/.idapro/loaders/iboot-loader.py", line 202, in accept_file
image_type= fd.read(0x30).decode()
^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'decode'
When I followed the logic in a Python interpreter (in IDA and externally) the offending code would return b'' which could be decoded, but when IDA is loading the file the behavior is different. To prevent this error being provided multiple times, I've added handling for the AttributeError exception that could occur.
