Package: planner
Version: 0.14.6-7
Severity: important

planner segfaulted me shortly after starting it for the first time
(upon inserting a new task); now, it segfaults upon each attempt to
start it.

Thanks for the report; unfortunately I cannot reproduce it.  And
that's an abort, not segfault.  Could you please run the planner
executable in gdb with --g-fatal-warnings?

Sorry for mixing the two up. Here's a trace with --g-fatal-warnings.
ON this occasion the crash happened when I attempted to resize the
window.  Some additional context:  was running in a GNOME/Wayland
session. I'm going to try GNOME/Xorg now.

Trace:

(gdb) set args --g-fatal-warnings
