Application that crashed: konqueror Version of the application: 4.3.2 (KDE 4.3.2) KDE Version: 4.3.2 (KDE 4.3.2) Qt Version: 4.5.2 Operating System: Linux 2.6.32-rc5-custom i686 Distribution: Ubuntu 9.04 What I was doing when the application crashed: when opening youtube content with latest webkitkde (svn 1039635), konqueror is able to open the applet and start the video, but as soon as video/audio starts (after the inicial cache process), konqueror crashes. if i go to adobe.com i can see the videos and flash tests with webkitkde without a problem, so it appears to be a youtube specific thing. -- Backtrace: Application: Konqueror (kdeinit4), signal: Segmentation fault [Current thread is 0 (LWP 25011)] Thread 9 (Thread 0xae26ab90 (LWP 25058)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb5d4c412 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb5f32344 in pthread_cond_timedwait () from /lib/tls/i686/cmov/libc.so.6 #3 0xb766545c in QWaitCondition::wait (this=0x93b9ac8, mutex=0x93b9ac4, time=30000) at thread/qwaitcondition_unix.cpp:85 #4 0xb765aa96 in QThreadPoolThread::run (this=0xb605948) at concurrent/qthreadpool.cpp:140 #5 0xb7664442 in QThreadPrivate::start (arg=0xb605948) at thread/qthread_unix.cpp:188 #6 0xb5d484ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0 #7 0xb5f2349e in clone () from /lib/tls/i686/cmov/libc.so.6 Thread 8 (Thread 0xada1db90 (LWP 25077)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb5d4c412 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb5f32344 in pthread_cond_timedwait () from /lib/tls/i686/cmov/libc.so.6 #3 0xb766545c in QWaitCondition::wait (this=0x93b9ac8, mutex=0x93b9ac4, time=30000) at thread/qwaitcondition_unix.cpp:85 #4 0xb765aa96 in QThreadPoolThread::run (this=0x9943d88) at concurrent/qthreadpool.cpp:140 #5 0xb7664442 in QThreadPrivate::start (arg=0x9943d88) at thread/qthread_unix.cpp:188 #6 0xb5d484ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0 #7 0xb5f2349e in clone () from /lib/tls/i686/cmov/libc.so.6 Thread 7 (Thread 0xaeedeb90 (LWP 25114)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb5d4c0e5 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb5f322ed in pthread_cond_wait () from /lib/tls/i686/cmov/libc.so.6 #3 0xb00e278f in ??

What version of the WebKit KPart are you using?
(In reply to comment #1) > What version of the WebKit KPart are you using? He stated svn r1039635 in his report. Currently the only known crash in kdewebkit as related to flash is due to the use of custom useragent string. However, that only happens when you leave a site that contains flash content, not during viewing as you reported here. Anyhow, I am unable to duplicate this crash. Viewing flash videos on youtube.com or anywhere else for that matter works fine here. Perhaps a Ubuntu specific issue ?
I have the same problem. Some videos on youtube work, but this doesn't: http://www.youtube.com/watch?v=M-hyxTuh2YE It loads the flash plugin and then crashes.

The link in comment #3 works fine here as well. I am unable to duplicate the crash...
I just compiled Qt 4.5.3 and the problem didn't go away. I have current svn revision of webkitkde, konqueror 4.3.2 and adobe-flash 10.0.32.18. Gentoo here. I'd say it's a qt-webkit problem, but everything works fine in arora...

Gentoo here. > > I'd say it's a qt-webkit problem, but everything works fine in arora... Well it works fine here on an Arch Linux box with the same versions of the software you specified. The backtrace you posted previously does not contain any useful information so it is of now use. However, the original backtrace seems to point to a crash deep in WebCore code itself which would be an upstream issue, but the fact that it works on arora makes it hard to state that... Can you compile kdewebkit with the following flag, -DCMAKE_BUILD_TYPE="RelWithDebInfo", and test the site to see if the crash get contains more useful information ? Also do you by any chance have nspluginwrapper installed ?
Created attachment 38014 [details] konqueror crashes on specific youtube videos Doesn't seem to contain any useful information.
Created attachment 38015 [details] output of the svn konqueror (r1043587) It's the entire output from konqueror. Contains the startup and loading of my homepage /home/devel/home.html. Then I went to the youtube page.
First, I compiled kdewebkit with relwithdebinfo flag, but crash information was the same as the one I already posted. Then I compiled svn kdelibs, konqueror and webkitkde with debugfull flag. The crash report, that Konqueror gave me, appears to be of no use. But the output of konqueror seems to make sense. Both files are in attachment.
(In reply to comment #6) > Also do you by any chance have > nspluginwrapper installed ? No, I don't have nspluginwrapper. I have 32bit x86 system.
I got it! It's because of the AdblocK filters! Youtube tries to insert ads into the video, konqueror blocks them and crashes.
Created attachment 38017 [details] These are my AdblocK filters When I disabled AdblocK, the youtube page worked as expected :)

I did run into this issue before but completely forgot about it indeed... The backtraces are usless because the crash happens in the flashplayer itself unfortunately. It is curious why that is the case though... Will have to investigate to see if there is anything that can be done at this level to mitigate/solve the issue.
I can confirm this, after i disabled adblock, konqueror stopped crashing. great work in spotting this elusive bug. best regards.. waiting for a fix in svn :)
