Version: (using KDE 4.2.1) OS: Linux Installed from: Debian testing/unstable Packages A website opened a popup window. I switched back to the main page and chose some other link, which would load a different page in the same popup window. I switched to the popup window and Konqueror crashed.

This may be related to bug 181421 or bug 172692. Do you recognize the situations? Thanks for reporting
No, it's not similar to one of the mentioned situations. In the mean time I have upgraded to 4.2.2 (from Debian unstable packages). I can reproduce the crash. Unfortunately it happens in the internal only area of an online banking site, so I can't share the URLs. Maybe I can describe the situation more thoroughly: * On the main page I choose a link. It opens a popup window (separate window, not tab) with additional information. * I quickly switch back to the main window using alt-tab while the popup window still loads (it's completely white). * I select a different link on the main page. It tries to load different content into the same popup window. * As soon soon as I try to switch back to the popup window using alt-tab, Konqueror crashes. The website uses Javascript functions window.open() and .focus() to control the popup. I get a different trace with 4.2.2: Anwendung: Konqueror (konqueror), Signal SIGSEGV [Current thread is 0 (LWP 23788)] Thread 2 (Thread 0xb1942b90 (LWP 23978)): #0 0xb7f25424 in __kernel_vsyscall () #1 0xb7d9a5b1 in select () from /lib/i686/cmov/libc.so.6 #2 0xb70fe670 in QProcessManager::run (this=0x8193098) at io/qprocess_unix.cpp:301 #3 0xb702f52e in QThreadPrivate::start (arg=0x8193098) at thread/qthread_unix.cpp:185 #4 0xb62244e5 in start_thread () from /lib/i686/cmov/libpthread.so.0 #5 0xb7da210e in clone () from /lib/i686/cmov/libc.so.6 Thread 1 (Thread 0xb5ef6700 (LWP 23788)): [KCrash Handler] #6 0xb6817b08 in QApplicationPrivate::focusNextPrevChild_helper (toplevel=0x9390558, next=true) at kernel/qapplication.cpp:2336 #7 0xb681b618 in QApplication::setActiveWindow (act=0x9390558) at kernel/qapplication.cpp:2309 #8 0xb6884c7a in QApplication::x11ProcessEvent (this=0xbfe40b18, event=0xbfe4068c) at kernel/qapplication_x11.cpp:3081 #9 0xb68ae63a in x11EventSourceDispatch (s=0x8192900, callback=0, user_data=0x0) at kernel/qguieventdispatcher_glib.cpp:142 #10 0xb6270718 in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #11 0xb6273c7b in ??

The last backtrace looks like bug 167971 What Qt version are you using ? Thanks
I'm using Qt 4.4.3-2 from Debian testing/unstable
Assuming this is the same as #167971. If you can still reproduce with current KDE >= 4.6.3, please reopen *** This bug has been marked as a duplicate of bug 167971 ***
