Version: (using KDE 4.1.0) Installed from: Ubuntu Packages OS: Linux Clicking "Apply" after setting the "Threaded Message List" option in the Appearance>Message List settings often results in a crash. Even on those occasions where it does not result in a crash, the messages remain unthreaded in just about every folder (Sent Mail, for whatever reason, seems to work fine). The primary account in use for this is an IMAP one, though the problem also occurs on local folders.
I can confirm that behaviour with same software version. I couldn't find a cause why this happens sometimes and sometimes not. Here comes the backtrace: Application: Kontact (kontact), signal SIGSEGV (no debugging symbols found) [Thread debugging using libthread_db enabled] [New Thread 0xb4e41940 (LWP 6986)] [New Thread 0xb0c0cb90 (LWP 6996)] [KCrash handler] #6 0xb7411320 in ??
