Want to run nspluginviewer in valgrind? It's not easy. Here's how: - Trigger the plugin you want in konqueror without valgrind running. - ps awwww | grep nspluginviewer - Record the commandline, then kill -11 the process - close drkonqi - in a konsole, export ARTSDSP_MMAP=1 - run LD_PRELOAD=$TDEDIR/lib/libartsdsp.so.0:$TDEDIR/lib/libartsc.so.0 valgrind -v --num-callers=15 --error-limit=no nspluginviewer <commandline that you saved> - WAIT for four lines to be printed to the screen that start with: 5 ............ 6 ............ 7 ............ 8 ............ - QUICKLY go back to konqi, reload the plugin page. - You should see the valgrind konsole start to scroll lots of debug output. If it does not, then it probably not picking up the new nspluginviewer. Try again. - As long as you don't close this konqueror window, you should be able to keep rerunning valgrinded nspluginviewer without much trouble.
