kde-4.4.80 (4.5beta1) Kmail slow switching folders

[Colin J Thomson]

Hi,

The system has not been put through a long test yet, but the first thing I 
have seen is Kmail is very slow when switching between sub folders.

I have Kmail setup with many sub folders for various groups/lists I belong 
too, switching between these takes ~5 seconds

No changes made to the config since the update from 4.4.x 

kde-4.4.80 (4.5beta1) 
QT-4.6.2
Fedora 13

Anyone else seeing this?

Off to check kde.bugs later..
