2000-02-22  bertrand  <Bertrand.Guiheneuf@aful.org>

	* message-list.c (message_list_set_folder):
	fix to show a sample correct implementation.

	* camel-folder.c (camel_folder_get_subfolder):
	(camel_folder_create):
	(camel_folder_delete):
	(camel_folder_delete_messages):
	(camel_folder_list_subfolders):
	(camel_folder_expunge):
	(camel_folder_get_message_by_number):
	(camel_folder_get_message_count):
	(camel_folder_append_message):
	(camel_folder_copy_message_to):
	(camel_folder_get_summary):
	(camel_folder_get_message_uid):
	(camel_folder_get_message_by_uid):
	(camel_folder_get_uid_list):
	Check folder state (open/close) and raise an
	exception if it is not ok.

	* providers/mbox/camel-mbox-folder.c (_create):
	create the file and the path with two different
	names.

	* camel-folder.c (_create): handle the case
	when the folder name starts with '/'

	* camel-exception.c (camel_exception_new): use
	(void) instead of () in decl.

	* camel-exception.h: cosmetic fixes.

	* camel-exception.c (camel_exception_init): new routine.
	Fix a bug in mail/message-list.c


	* camel-folder.h: cosmetic changes.

	* camel-stream-b64.c (reset__static): added a
	reset method. Thanks message-browser to find
	so much bugs :)

	* providers/mbox/Makefile.am (libcamelmbox_la_LIBADD): readd
	Unicode libs.

Fixes and exception handling in camel-folder.
Fixes in mail/evolution-mail to make it not
segfault and to demonstrate a correct implementation.
