Yes that should do the job... but.
I did a little further debugging by instrumenting messages.C as
follows:
107 string const get(string const & m) const
108 {
109 if (m.empty())
110 return m;
111
112 char * old = strdup(setlocale(LC_ALL, 0));
113 char * n;
114 if (lang_.size() < 100)
115 n = setlocale(LC_ALL, lang_.c_str());
116 else {
117 n = setlocale(LC_ALL, string("en_US").c_str());
118 lyxerr << "error:" << lang_.size() << " " << m << std::endl;
119 }
120 const char* msg = gettext(m.c_str());
121 setlocale(LC_ALL, old);
122 free(old);
123 // If we are unable to honour the request we just
124 // return what we got in.
125 return (!n ? m : string(msg));
126 }
Creating a Note inset, a Minipage inside it, and copying pasting the
latter, I get:
error:1932487777 Close
error:1932487777 Cancel
error:1932487777 Minipage Settings
(the number value doesn't change on recompile)
It turns out that the trouble is caused by three localized strings:
1) in frontends/xforms/dialogs.C the build() routine:
153 dialog->bc().view(new xformsBC(dialog->bc()));
The call to xformsBC has two default string parameters, see
frontends/xforms/xformsBC.h:
22 class xformsBC : public GuiBC<FL_OBJECT, FL_OBJECT> {
23 public:
24 ///
25 xformsBC(ButtonController const &,
26 string const & = _("Cancel"), string const & = _("Close"));
...and then there are the Form*.C files, e.g. FormMinipage.C:
34 FormMinipage::FormMinipage(Dialog & parent)
35 : base_class(parent, _("Minipage Settings"))
36 {}
This is where the three strings come from.
Does this ring any bells?
But remember also that *pasting* the dialog'ed inset is mandatory to
get the invalid lang_. Create the same inset geometry the regular way
will *not* produce it.
BTW the above kludge does *not* work. No difference. So the
Messages::Pimpl instantiation is existing, but lang_ is messed up.
