Comment 54 for bug 1881380

Hi,
I enabled proposed updates and updated my packages to:

libfprint-2-2:amd64 (1:1.90.2+tod1-0ubuntu1~20.04.1)
libfprint-2-tod1:amd64 (1:1.90.2+tod1-0ubuntu1~20.04.1)

And I can confirm that enrollment of fingerprints now succeeds:

$ fprintd-enroll
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-stage-passed
Enroll result: enroll-stage-passed
Enroll result: enroll-completed

However, trying to use su or sudo after this returns another error:

$ LANG=C sudo ls
Swipe your right index finger across the fingerprint reader
free(): double free detected in tcache 2
Abortado

$ LANG=C su
Swipe your right index finger across the fingerprint reader
free(): double free detected in tcache 2
Abortado

Should this be addressed in another bugtrack or can it be solved on this one?

Thank you.
