Description René Krell 2009-08-27 16:49:13 UTC

Version:           1.12.1 (using 4.3.00 (KDE 4.3.0) "release 158", KDE:KDE4:Factory:Desktop / openSUSE_Factory)
Compiler:          gcc
OS:                Linux (i686) release 2.6.31-rc7-4-desktop

This happens the last few weeks in Kontact with kmail:

Kontact becomes almost unresponsive on fetching  mail, mostly (but not only) after Kontact is started. I have an IMAP account to a server in our LAN. Right on startup, if the IMAP account is accessed by kmail automatically, the whole Kontact hangs for several minutes. Kontact and all its plugins are unusable during this time and almost not respond on any input. This problem occurs repeatedly each time interval fetching starts.

I confirm described behavior.

Comment 2 René Krell 2009-12-28 12:29:28 UTC

In version 1.13.0 (KDE 4.4 Beta2) the behaviour is slightly better. KMail is far more responsive during IMAP fetching and I'm thinking about to mark this as working for me. Commenters, please tell your opinion about that.

There is a problem that kmails mail fetching thread is not seperated from the GUI. This is one of the most hated bugs in this bugzilla. It will be fixed with the move to akonadi in KDE 4.5. So this can be fixed. 
The question is why kmail takes so long to fetch mails for you

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.
