Description Friedrich W. H. Kossebau 2007-08-31 11:49:35 UTC

Version:            (using KDE KDE 3.5.7)
Installed from:    SuSE RPMs

With the enterprise version KMail seems to (re-)scan all folders on every startup (local folders, no IMAP). At least the system goes down for quite some time (>15 min for me) with full disk activity and a lot of kio_file processes. Folder by folder over the time get their size set. Interaction with the system is very annoying.

Before upgrading from an older (>1 month) openSUSE package things worked alright.

KMail in trunk also has the folder size feature, but I don't see such problems there. There are one or two DirectorySizeJobsstarted, but nothing more.
Only the size of sent-mail, outbox and inbox is calculated at startup, not sure if that is different in enterprise.

CC'ng Till, as I think he wrote that feature.
