Version: 1.6.0 (using KDE 4.7.1)
OS: Linux
I few times since upgrading this laptop to KDE 4.7 (and moving from
Kmail to Kmail2) I've been unable to read email via imap. When I click
on a message it says "Retrieving folder contents, please wait"
indefinitely.
I tried exiting kmail and restarting it, but still had the same problem.
After stopping and starting akonadi using the Akonadi Server
Configuration KCM, then it was able to read mail (without restarting
kmail2 again).
Note: Akonadi version is actually 1.6.1, but I didn't see that option
under application version.
Reproducible: Sometimes
Steps to Reproduce:
Suspend laptop, resume laptop, check mail provided via an imap resource.
Actual Results:
"Retrieving folder contents, please wait"
Expected Results:
Mail retrieved so I can read it.

I get a similar problem, but generally on all kinds of Akonadi resources
immediately after KMail starts.
KMail version 4.7.1.
Akonadi uses an external, but local MYSQL server.

# 2) Set the variables below. However, in case you choose this method, then

What I've done:

- Stop MySQLd
- Reinstalled MySQL 5.1 as described above
- Added to my.cnf in section [mysqld] a line
wait_timeout = 31536000
- Start MySQLd
- Start Akonadi server
- Start KMail
Unfortunately It is still hanging.

For me it looks like KMail deadlocks when viewing messages while resyncing resources, even if clicking on messages from other resources. In my case it was a resync of a Local KMail folders resource.
After resyncing was done KMail displays all messages again, but very slowly, it takes up to a few seconds to view messages.
I still don't overlook how to best reproduce it, maybe you got a hint for me.

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 xxx at yyy.zzz because there is no email content"
akonadi_mixedmaildir_resource_1(24826)/akonadiresource (maildir): "Cannot add email to folder xxx at yyy.zzz because there is no email content"
and later:

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."

Once I start it kmail shows the messages. Then I browse around the folders to display random messages: after several clicks it starts slowing down and after a few more it gets stuck totally. From that point on no more messages are viewable
(even the ones that were visible before can't be viewed).
When the bug is triggered (that is kmail displays the "Retrieving Folder Contents" message for the first time) the resource stays quiet for some seconds and then spits out a lot of messages similar to this one:

>From that point the resource is stuck. The error messages from a

I haven't found a clear and systematic way to reproduce the issue.
Earlier I've reproduced it by opening a specific folder and clicking an email inside it. But then after a restart the same action didn't trigger the problem.
However it might be something related to timing. In particular I can trigger it very easily shortly after the akonadi server and mysql have been restarted. This is possibly because the caches are empty and take time to be filled. After I kill and restart the mixedmail resource several times, however, the bug hits less and less until I can
browse all my folders and view all my messages.
Weird.
