Errors with srt_fixer_gui

[jsavage]

Executing this results in the GUI being displayed. After populating the inputs and pressing Fix Subtitles appears to work as I see Subtitles fixed Successfully and a file manager then opens and the first two messages appear. When file manager is closed the third message appears. The gui then closes without further error. Stdout msgs:
~/srt_fixer_gui $ python srt_fixer_gui.py

That is an issue with your Gtk Theme.
Does the CLI version work? What version of python are you on?

You can try to overload the ttk widgets by adding import tkinter as ttk below line 18

so

from tkinter import ttk, filedialog
import tkinter as ttk

If you point me to the distro you are using, I can try to reproduce it in a VM
