Running msgfmt.py with the attached po file will produce an incorrect context for the entry "test".

Looking at the script, we require a comment to follow a contexted section for the context to be cleared. The gettext documentation makes clear that all comments are optional, so this is not desired behaviour.

My reading of the gettext documentation has a "msgctxt" line applying only to the current entry, so it should be cleared once the last msgstr has been written for that entry.

I will endeavour to provide a patch within the next day or two.

Test po file included

And a patch:

After the end of a message entry the options for the next line are:
1. A comment - we already reset msgctxt to None here
2. A blank line - we can have empty lines anywhere we want, so do nothing
3. A new msgctxt line - Set msgctxt to the new context
4. A msgid - This is the current failing behaviour. Fix sets msgctxt back to None.
