I looked into this for a few hours the other day, but I haven't started
implementing. I don't think I'll get to it for 2.0.2. ;)

The correct fix is to enable some infrastructure for context-specific
translations. The problem there is one of backwards compatibility. I
*think* we need to do something along these lines:

Add code to detect pgettext() support to Use some code for
xgettext() so that it'll extract the context if new enough, otherwise
just fall back to the string as-is. Use some sed magic on the .po files
to replace the msgctxt stuff with "context|string" for older versions.

Then have this:

const char *
purple_pgettext(const char *context, const char *msg)
	const char *translation;

	/* The translator had pgettext() and so does the user. */
	translation = pgettext(context, msg).
	if (strcmp(msg, translation))
		return translation;
	/* Try for combined context. The translator had pgettext(), but
	 * the user doesn't. */
	tmp = g_strconcat(context, "|", msg, NULL);
	translation = gettext(tmp);
	if (strcmp(msg, translation))
		return translation;

	return gettext(msg);

We'd universally call purple_pgettext() and everything should Just Work.
If a *translator* cares about context translations, they MUST upgrade
their gettext, but nobody else has to. This has the advantage over
glib-style "context|msg"-only translations of forwards-compatibility. If
at some point we wish to end support for older gettext installs, we can
simply remove the compatibility code and s/purple_pgettext/pgettext/.

I *think* this will work, but I need to start implementing to find out
for sure.
