I try with konqueror, and observe that following the steps mentioned in the original bug report, in the end (where ktorrent crashed) it shows me a pop-up dialog asking whether to close the window. So maybe the reported ktorrent crash was due to javascript closing window? (Google Chrome will not close the window, just show blank page, but I do not know if this is different implementation of the browser or different content sent to different browser - I am mentioning this because I have no idea which browser ktorrent claims to be, and I cannot be 100% sure if ktorrent gets the same content as konqueror...) Reassigning to konqueror people *** Bug 253351 has been marked as a duplicate of this bug. *** *** Bug 269076 has been marked as a duplicate of this bug. *** Is this still reproducible with Konqueror 4.8.4 or later? Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days, the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please set the bug status as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone! Hi Andrew,
Note this bug was never reproducible using konqueror, though ktorrent perhaps used konqueror web client/rendering engine.
Thus I can readily say that it is not reproducible using newer konqueror (the application, not the konqueror component/engine if there is such thing).
For the ktorrent application bug, I am not able to reproduce the bug for the following chain of reasons:
0. During writing the original bug report, I did not bother researching the actual reason for the crash further trusting that the developers could find it or confirm my hunch much quicklier as I had provided 100% reproducible method of triggering using the given URL.
1.The page mentioned 8 years ago in the original report does not exist any more.
2. Furthermore, my guess about the mechanism of the triggering events can not be tested using other page that would contain similar del.icio.us bookmarking widget as I am not able to quickly find one.
3. Even if I found one it might not work since del.icio.us seems to have some existential problems ("switching servers, back online July 24", but now is already September 23rd).
4. I have no idea how the page triggered its own death, maybe it was a pop-up window that was somehow passed its own reference that was used to close the window? I do not how to do that, I am not fluent in (client-side) JavaScript.
I suggest you just close the bug.
The other duplicated bug reports contained alternative ways to trigger apparently the same bug. I have some doubts about categorizing this as konqueror bug. Looks more like it might have been triggered by how the konqueror component close event was handled? I could not quickly find a way to open a web page using current version of ktorrent. The other bug reports mention web search function thing which I also could not find in the newer ktorrent. So it could be that it is not even possible to try to reproduce this bug because the functionality maybe is removed. |
Application: ktorrent (3.3.4) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-24-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: ktorrent comes with HTTP client. From a torrent page, I followed link to http://code.google.com/events/io/2010/sessions.html This page contains delicious.com bookmark button, which I pressed. Login, enter bookmark data, returning to the code.google.com page crash badabum. Note that the bookmark was saved, so the crash might have something to do with redirection. Kubuntu 10.04, up-to-date, no custom self-compiled or otherwise special KDE stuff installed. -- Backtrace: Application: KTorrent (ktorrent), signal: Segmentation fault [Current thread is 1 (Thread 0x7fe34bca3760 (LWP 3263))] Thread 6 (Thread 0x7fe33e508710 (LWP 3265)): #0 0x00007fe3478dffe3 in select () at ../sysdeps/unix/syscall-template.S:82 #1 0x00007fe34b84668e in ??
