Comment 1 Martin Flöser 2012-10-23 15:17:54 UTC 
Just tried to reproduce - no crash, maybe the deleting of message before is relevant
Comment 2 Laurent Montel 2012-10-24 06:51:08 UTC 
I already saw this BT but never can reproduce it too.
I add it to my todo :)
Regards
Comment 3 Martin Flöser 2012-10-24 14:54:59 UTC 
I found a further way to reproduce it (randomly) by just switching mail 
folders when in the folder one switches to the selected mail is the encrypted 
one.

Comment 9 Denis Kurz 2016-09-24 18:09:11 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 10 Denis Kurz 2017-01-07 22:35:02 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.
