Description of problem:

After update (2021-08-15) pango to version pango-1.48.8-1.fc34.x86_64
"Zim wiki" (Zim-0.73.5-1.fc34.noarch) crashes when opening page with "done
checkbox" eg.:

[ ] sth todo - this is ok
[*] sth todo - this crashes Zim

or page with a strike format
https://github.com/zim-desktop-wiki/zim-desktop-wiki/issues/1548

When I downgrade pango to version pango-1.48.4-1.fc34.x86_64, Zim works ok.
$ sudo dnf downgrade pango-1.48.4-1.fc34.x86_64

Version-Release number of selected component (if applicable):
pango-1.48.8-1.fc34.x86_64
Zim-0.73.5-1.fc34.noarch

How reproducible:

Steps to Reproduce:
1. dnf install pango-1.48.8-1.fc34.x86_64
2. dnf install Zim-0.73.5-1.fc34.noarch
3. Open Zim, write todo list eg:
[ ] asdf
4. click on [ ] to change it as "done task"  (or press F12) 

Actual results:

From terminal: 
Floating point exception (core dumped)

From journalctl:
sie 18 08:08:14 jedral.fedora.hp systemd-coredump[20877]: Process 19845 (zim)
of user 1000 dumped core.
