I "upgraded" to kmail 2.1.0 (kde 4.6.4) (running on
gentoo linux system).

It sort of works (to my amazement). I can connect
to my imap server, send and receive mail etc.

My problem is that the local folders (now for some
reason called kmail folders - why destroy the useful
information in the name of these folders I wonder?)
refuse to remember that messages have been read.

This is of course after importing from my old kmail
mail files. In every local folder a few messages persistently
show up as "unread". If I read these messages the unread
marker disappears.

But on the next kmail start up all these messages are back
to appearing as "unread".

Anyone have any idea how this might be fixed.

thanks in advance,

I thought that I could "work around" the persistent
unread mail markers on old messages by copying
them to a new folder.

Not such a good idea.

Now I've lost the data in my messages. Kmail still
sees the headers but will not display the messages
themselves.

Even after restoring a good copy of the file at issue and
"updating folder" the message content still does not
display.

If I start kmail from a console, I get lots of errors like this:

Code: Select all

"/usr/bin/kmail(2939)" Soprano: "org.freedesktop.DBus.Error.ServiceUnknown - The name org.kde.nepomuk.services.nepomukstorage was not provided by any .service files"
"/usr/bin/kmail(2939)" Soprano: "QLocalSocket::connectToServer: Invalid name"
"/usr/bin/kmail(2939)" Soprano: "org.freedesktop.DBus.Error.ServiceUnknown - The name org.kde.nepomuk.services.nepomukstorage was not provided by any .service files"
"/usr/bin/kmail(2939)" Soprano: "Unsupported operation (2)": "Invalid model"

what a piece of work is kmail

It appears that Nepomuk has crashed. To recover from this, please close all KDE PIM applications, then run the following:

Code: Select all

akonadictl stop
qdbus org.kde.NepomukServer /nepomukserver quit
sleep 10s
nepomukserver &> /dev/null &
sleep 5s
akonadictl start

Once Akonadi has started back up, try opening KMail and your other KDE PIM applications.
