Version: 4.1.1 (KDE 4.1.1) (using 4.1.1 (KDE 4.1.1), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.26-5-generic To reproduce: -Run Konqueror and click on: <settings> <configure konqueror> <file associations> on the right side click on <application> <pdf> -Remove all filetype associations from pdf. -Add a new one. (Just choose Okular or whatever) -Crash It only seems to happen with mimetypes that have completely empty association lists. This crash is not reproducible with mimetypes that have a greyish "None" entry. Here's the backtrace: Application: Konqueror (konqueror), signal SIGSEGV (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [Thread debugging using libthread_db enabled] [New Thread 0xb60978d0 (LWP 5278)] [KCrash handler] #6 0xb2223cac in ??

Thanks for the bug report. I can confirm this on 4.1.1 and trunk rev. 856793.
