SUMMARY


STEPS TO REPRODUCE
1. Receive an email with a specific subject line.
2. Accidentally send an email to someone with same subject line as in step #1
3. Receive a reply from the original recipient from step #2

OBSERVED RESULT

Kmail will associate the reply from step 2/3 with the unrelated email received in step 1, if the subject lines are identical.  This causes potential grouping of unrelated emails.  


EXPECTED RESULT

No association between emails from step 1 and steps 2 and 3.
