Compiler:          gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu11)

When I receive an email in kmail, it sometimes gets corrupted (about 30% chance). The list of emails says then that the mail has "no subject", sender "unknown", date "unknown". When I open the mbox file with a text editor, I notice that an empty line is inserted in the X-KMail-MDN-Sent header field. Once I remove the empty line (and the trailing garbage in the next line), Kmail recognizes the other header fiels.

My workaround is to manualy edit each file that contains a concerned email, but this is not an option in the long run.


Unfortunately, I got no idea how to reproduce this really annoying bug. I know that others have been trying to make it reproducible (see e.g. bug 86302) and failed.

I attach an example email where I replace personal information with the same number of X (since someone suggested it might be an issue of how many characters are used in the header).
