Hi,

Reported on NvDA translations mailing list and subsequently confirmed: NVDA 2018.4 fails to start properly if UI language is set to Aragonese.

Steps to reproduce:

1. Install NVDA 2018.4 and current alpha.
2. From NVDA settings/General, switch language to "Aragonese" and press Enter, and confirm if asked to restart.

Actual behavior:

The following traceback is recorded:

CRITICAL - main (11:26:22.013):
core failure
Traceback (most recent call last):
File "nvda.pyw", line 233, in
File "core.pyc", line 390, in main
AttributeError: 'NoneType' object has no attribute 'Language'

Expected behavior:

NVDA starts properly with language set to Aragonese.

System configuration

NVDA installed/portable/running from source:

Installed

NVDA version:

2018.4

Windows version:

Windows 10 Version 1809

Name and version of other software in use when reproducing the issue:

None

Other information about your system:

None

Other questions

Does the issue still occur after restarting your PC?

Yes

Have you tried any other versions of NVDA?

Yes - alpha.16458.

Technical information:

Not all languages come with wx.LanguageInfo, and Aragonese is one of those that isnt' supported by wxPython natively. Thus see if wxLang itself is something and act accordingly.

Thanks.
