Version: 1.9.5 (using KDE 3.5.5 "release 45.6" , openSUSE 10.2) Compiler: Target: x86_64-suse-linux OS: Linux (x86_64) release 2.6.18.8-0.7-default I have a folder with 80000 items in it. I right click on it and transfer to trash. It transfers about half the items and then the application crashes.
Could you upgrade to OpenSuse 10.3, kmail has got a lot of fixes since version 1.9.5.
Please add the backtrace to the crash (and reopen then), we need one to check if it is already reported or not. See http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports.
