Subject: planner: segfaulted; now segfaults on every start-up

Date: Fri, 26 Apr 2019 12:16:02 +0100

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:

Actually i mave have already been in GNOME/Xorg rather than Wayland,
unfortunately I cannot be sure now. The following happened on my next attempt
to use planner, definitely in an Xorg session this time. I did not set the
--g-* argument. SEGV happened when editing a text field "Name" in the "edit task"
dialog.

I fired up planner 0.14.6-7 for the first time since my buster update
and this same issue is happening constantly.

I think you should be able to reproduce it reliably by moving the window
to the upper left-hand corner for example and resizing the lower
right-hand corner to the lower right-hand corner of your desktop. If it
hasn't crashed already, while still resizing, move the mouse in circles.

In the meantime, I'm avoiding resizing the window and saving every time
I make a change and running planner in a while loop in the shell to make
the program somewhat usable.

Package: planner
Followup-For: Bug #928029

Dear Maintainer,

I experience the same problem. My system was also migrated from stretch
to buster (which seems to be the case for the first report).
Removing the configuration in .gconf/apps/planner did not resolve the
issue.

The problem seems not to exist in version 0.14.6-5. Maybe this helps
people that need to work with planner.
