*** Bug 325329 has been marked as a duplicate of this bug. ***
Thanks. Two people mentioned this now, though I still can't reproduce it. Can you clarify some information: - does it happen every time? - did you click on a 'metacontact' or expand the tree and select someone?
As I mentioned originally, it happens "every time" - though I can understand skepticism on a bug report :) I just tried it again, and it happened exactly the same again. The top two groups of contacts always come up already open, so I click directly on a contact, it seems like any contact, and I get this crash. Thankfully, it's after the conversation window shows up, so it's not like the application has gone completely useless on me, just kind of annoying :)
Thanks! I think I've fixed it. https://git.reviewboard.kde.org/r/113126/
I've patched my system with the above patch. I think you've fixed it, too. Crash is gone. Doesn't mean I understand the diff, just that I applied it and it seems to work here. (Gentoo made this easy.) Thanks!
Git commit ea6e30c0e838039e595f48e3f865bdcef14b7961 by David Edmundson. Committed on 06/10/2013 at 01:27. Pushed by davidedmundson into branch 'master'. Fix crash caused by TextChannelWatcherProxyModel void KTp::TextChannelWatcherProxyModel::onChannelMessagesChanged() void KTp::TextChannelWatcherProxyModel::onChannelInvalidated() emit dataChanged() using indexes from the wrong model. Because it's an QIdentityProxyModel it never causes any harm, but it's still "wrong" so Qt asserts break in the grouping model.
