Version: (using Devel) Compiler: debian gcc 4.3.2 OS: Linux Installed from: Compiled sources I initially had a few windows open, and one window had too many tabs open so I went to close them, getting to one that was empty (no page, no url, no about:blank) konqueror froze for a few seconds then crashed, restarting and trying to close said tab again crashed konqueror, never did get a backtrace for those, but now loading that last session causes a crash just after all the pages load: #
