Comment 31 for bug 862483

Message display hangup

I also have this bug.

When I click on a message in a folder it isn't displayed at all.

Earlier some of the messages were displayed after a long time
(minutes) and I also had a "KMail Folders: Aborting" progress item
stuck at 0% which won't go away when the "minus" sign was clicked.
(See the attached screenshot).

After I restarted kontact+akonadi the situation got worse an
no message is displayed anymore.

It seems that akonadi is doing something in the background (no clue
what since I did nothing really special except checking mail recently).
In the output I see a lot of error similar to:

akonadi_mixedmaildir_resource_1(24826)/akonadiresource (maildir): "Cannot add email to folder <email address hidden> because there is no email content"
akonadi_mixedmaildir_resource_1(24826)/akonadiresource (maildir): "Cannot add email to folder <email address hidden> because there is no email content"

and later:

request for item 139893 "1323434706.R514.spyro:2,S" failed: "Unable to retrieve item from resource: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
ItemRetrieverException : Unable to retrieve item from resource: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
posting retrieval request for item 139803 there are 1 queues and 0 items in mine
request for item 139803 still pending - waiting
processing retrieval request for item 139803 parts: ("RFC822", "HEAD") of resource: "akonadi_mixedmaildir_resource_1"

In the ps output I see that all the resources seem to be running.
The nepomuk email feeder process is using 66% of the CPU and 200MB
of RAM (but nepomuk is disabled here).
