dump after crash
KTorrent 3.1.2 from KDE 4.2.0 crash during some hours on seeding many torrents and leeching one torrent. $uname -a Linux zabivator 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux dump in attachment KTorrent 3.1.2 from KDE 4.2.0 crash during some hours on seeding many torrents and leeching one torrent. $uname -a Linux zabivator 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux dump in attachment If it's Qt bug was this reported to TT? I can easily reproduce this crash in Kopete (with Qt 4.5). The executeDelayedItemsLayout workaround works. But does the Kopete issue also happen with Qt 4.4? The KTorrent one does. These may actually be different bugs. Digging through my mail I found this on a kde-devel thread : http://www.qtsoftware.com/developer/task-tracker/index_html?id=245352&method=entry So it looks like this is fixed in Qt 4.5 Note, that the workaround above didn't completely fix it, I have now resolved it by ditching QSortFilterProxyModel, and doing the sorting myself. Kevin, I can't test right now with Qt 4.4, because I don't have Qt compiled.
Joris, the TT looks like different bug, the backtrace of Kopete crash goes through viewportEvent

and as I said the workaround works for Qt 4.5, I didn't saw any other crashes yet, but we don't use model/view in Kopete for a long time. So it looks like it wasn't reported if so I'll report it.
