PTXprint error when changing language

Question

We have just installed 2.5.12 and get an error when changing the language.

My team member can't change to Arabic.

I uninstalled and reinstalled and can't change to English, it automatically chose the first language, Arabic.

The error is

Traceback (most recent call last):
  File "ptxprint.py", line 381, in <module>
AttributeError: 'GtkViewModel' object has no attribute 'configId'

PTXprint Version 2.5.12

Then again from Unhandled exception in script

Failed to execute script 'ptxprint' due to unhandled exception:
'GtkViewModel' object has no attribute 'configId'

Traceback (most recent call last):
  File "ptxprint.py", line 381, in <module>
AttributeError: 'GtkViewModel' object has no attribute 'configId'

Answer 1

Well... I can confirm the bug. I'll put in a bug report on github.
There's a work-around to setting it, if you can figure out where ptxprint_user.cfg is stored on your machines (On linux, it's in ~/.config/ptxprint/ptxprint_user.cfg), that's a text file and you're looking for the line which starts lang=

e.g. on mine it says "lang=en.UTF-8" for English, I guess ar.UTF-8 for Arabic.
Needless to say, make a backup of the file first!
