--- Comment #2 from Rodney Baker <[email protected]> --- In version 5.4.2 this behaviour has now changed. The message is still never displayed, but at least KMail does not hang, and if I open the message and select "View Source" I can view the entire message (and it loads very quickly). Nothing I can do, however, makes it display in the preview window or by opening the message, except when viewing the message source. -- You are receiving this mail because: You are the assignee for the bug.
