Description Thomas Fischer 2009-08-14 19:41:16 UTC 
Version:           1.11.4 (using KDE 4.2.4)
Compiler:          gcc (Gentoo 4.3.2-r3 p1.6, pie-10.1.5) 4.3.2 CFLAGS="-O2 -march=prescott -pipe"
OS:                Linux
Installed from:    Gentoo Packages

When accessing an IMAP account (not DIMAP), for some mails the message list view does not show all header information properly (e.g. subject), whereas the message view for the same email displays all information correctly.
In my example, for some emails the subject is shown as "(No Subject)" and the date is set to "Unknown". Clicking on the mail (thus showing it in the message view) updates the date to the correct value, whereas the subject stays "(No Subject)".

It is not obvious why some mails are affected and others not.
Corruption of the IMAP database can be excluded as when accessing the IMAP account via webmail no problems occur.

Screenshot visualizing behavior will be attached to bugreport.

The problem here seems to be a corrupted mail folder index.

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.
