When I read a message and kmail wants to moved it later by filter it can happen, that the read status has changed. In this case kmail shows a useless dialog by claiming about the read status. Please omit this dialog in this case because this is not a real conflict for the user. See attachment. Reproducible: Always
Created attachment 86054 [details] conflict dialog showing the useless changed read status
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.
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.
