Description of problem:

I've noticed instant crash of a pidgin - with this new pango 1.45 package.
I've downgraded to version  pango-1.44.7-3.fc33  and pidgin is 'usable'
again (aka I can click on URL without getting instant core dump).

This is backtrace I'm getting on a crash:
(pidgin 2.13.0-20)

whats the exact pango version ? I believe 1.45.3 should have all reported
crashers fixed.

It seems gtkimhtml.c is from pidgin code, and it crashes when show the url
tooltips.

It seems there is pidgin 2.14.1 in upstream.

URL: https://sourceforge.net/projects/pidgin/files/Pidgin/

Could you ask pidgin maintainer to update the package?

This looks curious. length is 200, but "http://sources.redhat.com/lvm2" is
clearly shorter than 200 bytes.

Does this bug still happen in Fedora 34?

This message is a reminder that Fedora 33 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with
a
Fedora 'version' of '33'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 33 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
