Version:           Kontact
Version 1.3, KMail
Version 1.11.0 (using Devel)
OS:                Linux
Installed from:    Compiled sources

On clicking the IMAP inbox in the mail folder list, to look about new mails, kontact (kmail?) crashes. This happen every time therefore I can't use kontact/kmail any more. Days before it crashed only one or two times a day, since yesterday every time if I click on the inbox. The same IMAP account work with other mail clients (thunderbird, ...)

The back trace:
