#11 0x00007ff8b0a46367 in detectBlurRegion(QWidget*, QWidget const*, QRegion&) () from /usr/lib/x86_64-linux-gnu/qt4/plugins/styles/libbespin.so #12 0x00007ff8b0a495c3 in Bespin::Style::updateBlurRegions() const () from /usr/lib/x86_64-linux-gnu/qt4/plugins/styles/libbespin.so Can you reproduce this crash if you use some other style, e.g. oxygen? I think not Here another backtrace very similar to the previous one: Application: Konqueror (kdeinit4), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

And, I have been thinking and this kind of crashes always occurs when I shift from KHTML to Webkit in twitter, does not matter if I am using Bespin or Oxygen, I think it could be related to Webkit. This backtrace of this crash is in the theme engine you're using, bespin which Konqueror can do nothing about? Can you post the backtrace for the crash you get when you switch from KHTML to WebKit in twitter? You said that one crashes regardless of whether you using Bespin or Oxygen, right? As quick workaround, exclude "konqueror" from ARGB windows in "bespin config" Unfortunately the backtraece lacks line numbers, but what the function does is to recursively parse children of the window and for ::isWidgetType() ones check visibility, autoFillBackground, background color, WA_OpaquePaintEvent and whether they're QScrollBar or QProgressBar and add them or their mask to a region. -> Either there's a dangeling or a nullpointer in QObject::children() (the delayed update is protected by a weakpointer on the window and we're too deep in the recursion) Is facebook mandatory or did you encounter this when changing the render engine on other pages as well? Can you reproduce it by export QT_NO_GLIB=1 konqueror as well (notice that w/o the glib dispatcher eg. flash will likely stop to work) Notice that QtCurve and oxygen-transparent may have similar code. (In reply to comment #4) >Can you post the backtrace for the crash you get when you switch from KHTML to WebKit in twitter? I can't, that does not occur. It occurs, sometimes, from Webkit to KHTML (In reply to comment #4) > You said that one crashes regardless of whether you using Bespin or Oxygen, right? Yes, but now, I have noticed another thing: when I am in my timeline of twitter, using Besping not Oxygen as theme, with Webkit as engine, and in the same tab of Konqueror I type in the search bar another direction of twitter, for example, twitter.com/user, Konqueror crashes. It always occurs, and the backtrace is very similar. Maybe, really all this is related to Bespin: Application: Konqueror (kdeinit4), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I get crashes for "neither" (was on facebook & twitter but have no account for either and will certainly not create one) Can you compile bespin from svn or does Ubuntu ship debug packages for bespin? I have compiled bespin from SVN, I don't know how to determinate the revision... Created attachment 84457 [details]
Debug output for Bespin
"svn info"
Splendid, for that will allow you to add the attached patch to tell us where things crash.
Notice that it will print a lot of information to konsole - or .xsession-errors so i suggest to compile it in, run
konqueror > bespin.debug 2>&1
make it crash and attach the bespin.debug file (you'll eventually have to compress it)
OK
I have make this:
Applied patch to bespin.cpp
Ran: ./configure
cd build
make
sudo make install
If I have made a mistake, please let me know. Keep in mind, I am just a "desktop" user.
Next, I have ran:
konqueror > bespin.debug 2>&1
The file is attached (bespin.debug)
Also, I have noticed that the file configure of bespin svn, in line 64 has the command: ccmake, it obviously is wrong and gives an error by running ./configure:
$ ./configure

Seems you have cmake.

Bespin debug
I think not, the problem related to the line 64 of the configure file is not related. I have corrected the command from ccmake to cmake, compiled and installed Bespin again, and the crash is still reproducible There's a NULL object in the children list of apparently "kwebkitpart".
No idea what funky stuff happens to cause this, but that can of course be detected and skipped - i'll push a bespin update in a few minutes.
*Notice*, that this does not seem sane.
I'll bypass the known segfault, but guess that this should rather not happen - and may cause other segfaults, bespin or not.
-- OT --
"ccmake" is a curses ("text gui") frontend for cmake based reconfiguration
there's nothing "wrong", it's just not installed because ubuntu apparently separated it into a "cmake-curses-gui" package (while the script just assumes that if you got cmake, you "of course" also got ccmake)
-> r1709 Is it supposed that the crash is avoided with r1709? Yes. If not, you'll have to run the debug patch again. Sorry, I can't apply the patch this time, I get this error: $ patch --verbose < parche.patch Hmm... Looks like a unified diff to me...

Bespin debug 2
Updated debug patch.
So it still does crash in
detectBlurRegion(QWidget*, QWidget const*, QRegion&) () from /usr/lib/x86_64-linux-gnu/qt4/plugins/styles/libbespin.so
?
Sorry, I think I have fallen in a mistake. By using revision 1709 Konqueror does not crash. I can't reproduce the crash, now. Thank you so much, you are very gentle. Nevermind - I largely prefer that over a completely weird bug on top =) @Devs Any idea why kwebkitpart could have one (or two) NULL children? The function is entered by a timer and called for a list of non NULL QWeakPointer<QWidget>::data() and recursively their children() It *looks* as if i would jump into the destruction of kwebkitpart or a reparenting (with the child nulled, but not yet unlisted from children) -> Does kpartwidget move widgets (toplevel windows) to other threads? Or any other idea how this could happen? Thomas, do I understand you correctly, that the bug is in KWebKit part? Please set the bug status accordingly. I do not know where the issue is. What is known so far is that when one changes konquerors backend from Webkit to KHTML, there will -eventually- be a NULL QObject child in a visible kwebkitpart widget, what should be impossible but for a) a major bug in QtCore ... b) threading, but iirc it should not be possible to have a (visible or not) QWidget in a non GUI thread and children cannot be in a different thread than their parent either because removing is supposed to be atomic, deleting a child would remove it and that happens on a direct connection (so no chance for the timer to fire inbetween - where there also would be no NULL but a dangeling pointer) Something *is* fishy here, but i have not enough insight to point a culprit (could e.g. still be bespin as well) Unfortunately i was neither able to reproduce this for investigation :-( Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.
