Tested with version 4.2.4 on ubuntu 10.10 :

Many translatable strings are not marked for translation, missing in POT file.

Some examples :
=============================================================
from line 490- of tools/browser/schema-browser/table-columns.c:490--- :

	/* Colum: Nullok */
	renderer = gtk_cell_renderer_toggle_new ();
	column = gtk_tree_view_column_new_with_attributes ("Not NULL?", renderer,
							   "active", COLUMN_NOTNULL, NULL);
	gtk_tree_view_append_column (GTK_TREE_VIEW (treeview), column);

	/* Colum: Default */
	renderer = gtk_cell_renderer_text_new ();
	column = gtk_tree_view_column_new_with_attributes ("Default value", renderer,
							   "text", COLUMN_DEFAULT, NULL);
	gtk_tree_view_append_column (GTK_TREE_VIEW (treeview), column);

	/* Colum: Details */
	renderer = gtk_cell_renderer_text_new ();
	column = gtk_tree_view_column_new_with_attributes ("Details", renderer,
							   "text", COLUMN_DETAILS, NULL);

==========================================================================
tools/browser/schema-browser/table-info.c:339:	

tmp = g_strdup_printf ("In schema '%s'", schema);

===========================================================================
All the strings in the following file :

providers/web/web_specs_dsn.xml.in:6:    
<parameter id="PATH" _name="Path to 
PHP script" _descr="The path of the script to use if service is not at the web server's root" gdatype="gchararray"/>


===========================================================================
libgda/sqlite/xml_embedded.h:177

"    <parameter id=\"DB_NAME\" name=\"Database name\" descr=\"The name of a database to use (without the .db)\" gdatype=\"gchararray\" nullok=\"FALSE\"/>\n"
"    <parameter id=\"DB_DIR\" name=\"Directory\" descr=\"Directory where the database file is stored\" gdatype=\"gchararray\" nullok=\"FALSE\" plugin=\"filesel:MODE=PICKFOLDER\"/>\n"
"    <parameter id=\"LOAD_GDA_FUNCTIONS\" name=\"Extra functions\" descr=\"Enable usage of some extra functions in SQL\" gdatype=\"gboolean\" nullok=\"TRUE\"/>\n"
"    <parameter id=\"FK\" name=\"With foreign keys\" descr=\"Enforce foreign keys\" gdatype=\"gboolean\" nullok=\"TRUE\"/>\n"
"  </parameters>\n"
"</data-set-spec>\0<?xml version=\"1.0\"?>\n"


AND finally, menus and toolbar are still in English though the messages are translated in the PO files
(see BUG https://bugzilla.gnome.org/show_bug.cgi?id=634737 which can be reopen):
===========================================================================
tools/browser/browser-window.c: line 274-304
