Comment 3 Jeremy Bicha 2017-04-20 14:17:33 UTC

The crash reports are from gnome-calendar 3.24 on Ubuntu 17.04.

Are those reports from 3.24.0 (the released tarball) or gnome-3-24 branch? There are some commits that might have fixed that.

I believe commit 40993b1 fixed all the issues we used to have with the Week view. I also believe this is another symptom of the same issue that generated bug 781456 (and was also fixed by that commit). Could you please confirm that?

Meanwhile, I'll mark this bug as NEEDINFO.

Jeremy: Any possibility to confirm?
