Switching folders in KMail takes a while?

[Martin Kho]

Hi,

When I for the first time switch in KMail from one folder to another it takes a 
few seconds before the content is shown. Switching again to another folder 
doesn't have this delay. In .xsession-errors I get:

[akonadiserver] Error during executing query "SELECT PimItemTable.id, 
PimItemTable.rev, PimItemTable.remoteId, MimeTypeTable.name, 
ResourceTable.name, PimItemTable.size, PimItemTable.datetime, 
PimItemTable.collectionId FROM PimItemTable, MimeTypeTable, CollectionTable, 
ResourceTable WHERE ( PimItemTable.mimeTypeId = MimeTypeTable.id AND 
PimItemTable.collectionId = CollectionTable.id AND CollectionTable.resourceId 
= ResourceTable.id AND ( PimItemTable.id = :0 ) ) ORDER BY PimItemTable.id 
ASC" :  "MySQL server has gone away QMYSQL: Unable to execute query"

This happens on a full updated F12 system (kde 4.4.1, KMail: 1.13.1).

Any one else have seen this behaviour?
