The File Capture Fails When the Working Directory Has a File Called 'config.ini'

[barmanroys]

Describe the bug The file capture object fails to read a .pcapng file when the working directory has a specific file called config.ini. I was keeping some other configuration in a file of that name, as part of a packet processing pipeline. But seems somehow pyshark tries to access that file and looks for a section called tshark.

To Reproduce Code sample

#!/usr/bin/env python3
# encoding: utf-8
import pyshark as ps
filename:str = 'some_file.pcapng' # Any pcap file should serve the purpose to reproduce the error 
with ps.FileCapture(input_file=filename) as capture:
    print(capture[0].pretty_print()) # Fails when 'config.ini' present in the directory

Expected behavior I expect the above code to print the information about the first packet in the file.

Versions

• Ubuntu 20.04
• pyshark 0.5.3
• TShark (Wireshark) 3.2.3 (Git v3.2.3 packaged as 3.2.3-1)
• Python 3.8.10
