Comment (by murrayc@…):

 It seems to be a failure to convert the (probably) UTF-8 error message to
 the current locale's encoding, during the implicit conversion that happens
 here, in document.cc's get_file_display_name(), when writing to std::cerr:

   try
   {
     file_info = file->query_info(G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME);
   }
   catch(const Glib::Error& ex)
   {
     std::cerr << G_STRFUNC << ": uri=" << uri << "): error: " << ex.what()
 << std::endl;
     return result;
   }

 That is strange. Maybe it's because the error message contains a badly-
 encoded URI (based on a badly-encoded filepath?) for some reason.

 I guess we'd first want to know why Gio::File::query_info() fails the
 first time. The error message's explanation seems to be just "0", which is
 itself strange. I guess that something is odd about glib or the locale. I
 think this might need someone to debug the actual code as it happens.
