I'd suggest reporting to upstream, http://ktorrent.org/forum/viewforum.php?f=1&sid=ddd98bd09faf797c3cf5398cfdf592a3 (though it's a forum, for better or worse). I think i've reported that many times to kde.org and imo it's qt bug, falls into our laps anyway. Juha, can you please report this bug upstream and provide us the link here? http://bugs.kde.org/show_bug.cgi?id=174462 http://bugs.kde.org/show_bug.cgi?id=172198 http://bugs.kde.org/show_bug.cgi?id=173014 https://bugzilla.redhat.com/show_bug.cgi?id=465721 http://bugs.kde.org/show_bug.cgi?id=163631 Take a pick According to http://bugs.kde.org/show_bug.cgi?id=163631 this is not a ktorrent problem but a Qt problem, re-assigning. That's not the same bug as this one, the backtrace is completely different. The bug here looks like: http://bugs.kde.org/show_bug.cgi?id=172198 They claim it's fixed in 3.1.5, but it apparently isn't. Kevin, you're right, that bug looks much more alike. I reäassigned - again - and added this the KDE bug as an external bug reference. Is this still an issue with the newest release? If so please reassign to either F10 or F11 depending on which release the problem still exists. -- Steven M. Parrish - KDE Triage Master Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Upstream claims this is fixed. Can you still reproduce it? I don't think it happens anymore, we have now other crashes. |
