Version: 2.0.0-1ubuntu2 (using KDE 4.3.2) Compiler: gcc/g++ 4.4.1-1ubuntu2 OS: Linux Installed from: Ubuntu Packages I viewed a 700 MB video file (by pressing F3), closed it and Krusader still occupied 2 GB RAM, which it shouldn't. See also http://bugs.kde.org/show_bug.cgi?id=210629. This bug has been also reported here: https://bugs.launchpad.net/ubuntu/+source/krusader/+bug/451863
Can't reproduce it using 2.4.0-beta3. Feel free to reopen if the problem still exists in recent version.
