Segmentation fault when using custom formatting

[igor-sosnowicz]

Describe the bug
The application segfaults after creating a task with text containing formatting copied from the Internet. Before that a new task is being created (a number of task changes from 3 to 4 before freezing and shutting down unexpectedly). After restarting the program, the same scenario happens and the number of tasks increases by one, again.

To Reproduce
Steps to reproduce the behavior:

1. Create a new task with description containing text from the Internet with some custom formatting applied.
2. Add this task.
3. Let the project synchronise.
4. Try opening the project.

Expected behavior
It should create a single task and do not produce segmentation fault.

Thanks for the report! To help debug this, could you provide:

1. Which sync source are you using? (Todoist, Nextcloud/CalDAV, or local)
2. A sample of the text that causes the crash (or similar formatted text that reproduces it)
3. A backtrace if possible: coredumpctl debug planify then type bt full

This will help pinpoint where the crash is happening.
