Description Don Curtis 2017-07-28 13:48:50 UTC 
KMail/5.3.2 (Linux/4.4.74-18.20-default; KDE/5.26.0; x86_64; ; )

If a received e-Mail has a "To" header field without a colon then, KMail2 hangs for a while and then after a while begins to respond and, doesn't display the received message -- the "Attachments" panel only indicates a data amount indicated by the e-Mail's title.

Opening the .local/share/.local-mail.directory/ e-Mail file with a text editor and appending a colon (and a space for the KMail2 clear text to display "To:" in bold) to the "To" fixes the issue.

For example, part of a header received from Thunderbird running on a Linux platform before the "To" was changed to "To: ":

Yes, yes, I know: the Mozilla Thunderbird folks should conform to RFC 2822 but, in the case of e-Mails with a suppressed recipient list, they don't  . . .

--------------------------------------------------------------------
RFC 2822:
2.2. Header Fields

   Header fields are lines composed of a field name, followed by a colon
   (":"), followed by a field body, and terminated by CRLF.

With kmail2 5.10.3 this is still an issue …
