Version: (using KDE 4.3.2) OS: Linux Installed from: Ubuntu Packages Konqueror froze while I was browsing the web. It would redraw itself occasionally, but was unresponsive most of the time. GDB shows that Konqueror was making blocking DBUS calls: #0 0x00b10422 in __kernel_vsyscall () #1 0x059cfba6 in *__GI___poll (fds=0x5a50ff4, nfds=1, timeout=25000) at ../sysdeps/unix/sysv/linux/poll.c:87 #2 0x02e730fb in ??
