Version: 1.11.4 (using 4.2.4 (KDE 4.2.4), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.29-gentoo-r5 When I select a mail to be displayed in the preview pane, kmail locks for up to a minute hogging 100% cpu. This happens to mails having many small mime attachments. It also happens to plain text mails having only a few huge mime attachments. KMail completely locks during that time and is unusable. I can generally reproduce this behaviour with newsletters from GMX or StayFriends.de. HTML mails which load their contents from remote URLs usually render their contents fast without this UI locking. So I think the attachment/mime parser is simply slow (really slow).
Please take into consideration that fixing this bug may masquerade bug 195550 which I also encounter in combination with this one.
I guess this is one case more of bug 189961.
Yes indeed it sounds similar. However, my researchings of the bug lists didn't show that up. So you may link it as duplicate. I want to add that this happens on dimap and imap.
