[focal] gnome-calendar crashes when moving it full screen to another screen (SIGSEGV in gdk_rgba_to_string())

[Trent Lloyd]

I can consistently crash gnome-calendar by dragging it from one monitor over to the other monitor at the top of the screen so that it moves into full screen. It seems to move to that screen with the window resized but the contents not redrawn.

Focal with all updates as of 25-mar. Reproducible multiple times.

Thank you for your bug report, upstream reports indicates it's fixed in 3.36.1 which is the version included in focal, closing but feel free to reopn if you still have the issue with that update
