Marco crashed after closing MATE Tweak panel

[Aaron Pickett]

After rebooting following 20.04 beta install, I opened the MATE Tweak panel to see what compositor I was using (Marco adaptive. I closed this panel, and did nothing else. Shortly thereafter, marco crashed.

This crash has the same stack trace characteristics as bug #1863431. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.
