Steps to reproduce:

Note, set office to use a language other than English.

approach 1:

1. Open the word document provided in the attachment.
2. When you arrow on a comment press insert+alt+c,

approach 2 - listing all comments in the elements list:

1. press insert+f7, when in the browse mode,
2. in the filter radio buttons category, find comments.

Actual behavior:

When the first approach is used, the shortcut is not working, i.e. the comment was not read.
When you use the second approach, the following can be found in the log:

ERROR - queueHandler.flushQueue (19:54:49.137):
Error in func initElementType from eventQueue
Traceback (most recent call last):
  File "queueHandler.pyc", line 53, in flushQueue
  File "browseMode.pyc", line 902, in initElementType
  File "browseMode.pyc", line 922, in filter
  File "NVDAObjects\UIA\wordDocument.pyc", line 88, in label
TypeError: format() argument after ** must be a mapping, not NoneType

The comments are not listed

See code:

		if not obj.parent or obj.parent.name!='Comment':
			continue

The problem is that this object name is language sensitive i.e. in polish it is "Komentarz". So when the language in word interface is set to other than english, this condition is always true and NVDA doesn't see any comments even if there are some.

Expected behavior:

The chomments should be listed and read, when nvda+alt+c, and when ins+f7 is pressed
