Segmentation fault in ImportsModel::rowCount(QModelIndex const&) const

Also running Arch Linux (but with X11). Same error.

I don't have any handy archlinux but i have tested the current code from git on Ubuntu20 and builds and runs fine, i have also updated the README with the proper qt5 packages needed to build.

Could you share the pacman packages needed to build iaito by updating the README?

Can you provide a full backtrace from gdb or build iaito with asan to get a meaningful crashlog for me to make a blind fix for it?

thanks!

Possibly related to changes in Qt. Ubuntu 20.04 is on Qt 5.12, Ubuntu 20.10 is on Qt 5.14, Arch current is Qt 5.15.

There are a bunch of warnings of wrong c++ usage in some classes, and this is making qt6 builds crash, maybe this is the same issue you are having? I fixed many of those warnings already, can you see them in your archlinux build? Mind to try to fix them (or comment the affected code) to confirm the issue? Thanks!

It's just implicit fallthrough and defined but not used warnings

It's the same with and without asan. And yes I deleted the build directory.

Please confirm the fix :)

Can confirm this is fixed, thanks!
