--- Comment #4 from James Carthew jcarthew@gmail.com --- This is happening in wine-4.21 (Staging) and wine-4.21 (devel). When richedit20.dll from Windows/winetricks is enabled it crashes Jabber. When you use WINE's implementation of richedit20 the program launches/works but only the first letter of each message is sent.
