Thanks and yes this looks like a not so fun bug in the qmlengine :( I'll try to reproduce it locally I investigated a bit and it looks like it crashes because of a binding loop on checked: which causes a stack overflow. If I comment the 4 lines: //checked: pageStack.currentItem.type === TimelinePage.TimelineType.Home ... etc... in main.qml then it starts Same "QObject::connect(AccountManager, TimelineModel): invalid nullptr parameter" error after trying to start with an account created. It shows the windows for a second and then crash. Installed via flathub (org.kde.tokodon 22.09) ArchLinux up-to-date (2022-11-22) Not sure if this is a duplicate of https://bugs.kde.org/show_bug.cgi?id=461747 https://bugs.kde.org/show_bug.cgi?id=459577 and https://invent.kde.org/network/tokodon/-/issues/32 This was fixed with https://invent.kde.org/network/tokodon/-/merge_requests/69 Since you are using tokodon from git, I would appreciate some testing just to be sure :) |
Created attachment 153774 [details] Core dump SUMMARY The first few times I launched the app it worked and I could use it. But now it crashes every time before opening a window. Here is the Qt debug log of git head as of today: ```bash $ tokodon Loading any accounts from settings.
