Description Fabian Schoelzel 2009-09-16 22:04:15 UTC

Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Unlisted Binary Package

I have a maildir folder, which contains a total of 53425 mails from a mailing list (122,6 MiB). The folder is configured for a mailing list. When i have more than 1000 unread mails in this folder, it doesn't behave correct anymore. As soon as i click on that folder to view its contents, ...

- it processes all the mails (1-2 minutes)
- then it threads all mails (~30 seconds)

When i change to some other folder and then return to this folder, it happens again. As soon as i mark some mail as unread, so that i have less than 1000 mails unread, this behaviour goes away. If i get new mails, so that unread mails breaks the 1000 border again, this behaviour returns.

Please tell me if i missed some info.

Cheers,
Fabian

Thank you for taking the time to file a bug report.

KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
