Comment 1 Laurent Montel 2013-10-25 19:31:47 UTC 
second dialog was a bug (fixed)
For crash will look at
Comment 2 Denis Kurz 2016-09-24 18:17:58 UTC 
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Comment 3 Denis Kurz 2017-01-07 22:44:28 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
