Subject: * src/widgets/modest-recpt-editor.c:
X-Git-Tag: git_migration_finished~2784
X-Git-Url: http://git.maemo.org/git/?p=modest;a=commitdiff_plain;h=f8a806f78f538409b502f58f09f969186e908258

* src/widgets/modest-recpt-editor.c:
	* Now we discard invalid chars (bullets and images) on pasting
	  in recipient editor. This way, if we paste from the editor
	  these symbols, they should be removed from text pasted in
	  the recipient editor (fixes NB#62575).
