Version: (using Devel) Installed from: Compiled sources OS: Linux Konqueror has some serious problems when I hit Alt-Left or the 'Back' button. Go to some website, for example archlinux.org. Then click on a link, say 'Forums'. Then hit Alt-Left. Konqueror returns to the start page instead of the original archlinux.org as it should. OK, now hit Alt-Right and Konq crashes. Here's the backtrace (I'm using the most recent kdemod4 binary packages from Arch): Application: Konqueror (konqueror), signal SIGSEGV (no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1".

Works for me on Debian. konqueror -v Qt: 4.4.0 KDE: 4.00.74 (KDE 4.0.73 >= 20080515 Konqueror: 4.00.68 (KDE 4.0.68 >= 20080402) It works as expected, without crashing.
On my computer this crashes almost all the time (and even when it doesn't crash, going back doesn't work right). I hit Alt-Left and then Alt-Right and I get the crash. konqueror -v Qt: 4.4.0-rc1 KDE: 4.00.69 (KDE 4.0.69 >= 20080410) Konqueror: 4.00.69 (KDE 4.0.69 >= 20080410)
I just checked and I don't encounter any errors neither with 3.5.9 nor with trunk r810280 (20080520). @Przemyslaw: Please try upgrading to a more recent snapshot if possible so you can see if the bug is (hopefully) finally gone.
OK, I got KDE 4.0.80-1 and now this seems to work fine. :)
