Comment 3 Allen Winter 2012-01-12 23:45:26 UTC

adding Szymon to the CC. he may have an idea on this one.

Comment 4 Bernd Oliver Sünderhauf 2012-11-28 19:42:23 UTC

Think that this is a duplicate of Bug #282033

Comment 5 Denis Kurz 2016-09-24 18:17:43 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 6 Denis Kurz 2017-01-07 21:34:37 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.
