Version: 1.9.6 (enterprise 20070904.708012) (using 3.5.7 "release 72.9" , openSUSE 10.3) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.22.17-0.1-default I setup KMail to access my Gmail accounts using disconnected IMAP. To prevent downloading uneccesary email (i.e., from All Mail and Spam folders on Gmail), I decided to allow 'local subscriptions' on folders. Selecting the account and enabling 'Local Subscriptions' crashes Kmail.

This is not a useable backtrace. Furthermore, unsubscribing from the mentioned IMAP folders of my Google Account (both online and disconnected) works fine for me in the KDE4 version.
