Can't save as gif

[Toan Nguyen]

Ubuntu 19.04 Disco Dingo.

I can save recorded video as webm or mp4 but not as gif. The peek app from flatpak works fine so I suppose this is a problem in ubuntu package. This is the output when run in terminal:

Using screen recorder backend gnome-shell
Recording to file /home/dtoan/.cache/peek/peekR8UVZZ.webm
free(): double free detected in tcache 2
Aborted (core dumped)

Am facing the same issue

Status changed to 'Confirmed' because the bug affects multiple users.

Same here :( Right after updating to Ubuntu 19.04. Reinstalling Peek doesn't resolve this problem.

Same message in terminal :

free(): double free detected in tcache 2
Aborted (code dumped)

Problem appears when recording GIF and APNG only.

Same here:
Operating System: Kubuntu 19.04
KDE Plasma Version: 5.15.4
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2

You can fix it temporary by installing the package for next release:
https://packages.ubuntu.com/eoan/amd64/peek/download

E.g. for german Users:
http://de.archive.ubuntu.com/ubuntu/pool/universe/p/peek/peek_1.3.1-6_amd64.deb

The fix is released since peek 1.3.1-6, which exists in Ubuntu 19.10 and 20.04. For users of Ubuntu 19.04: Ubuntu 19.04 is now End-Of-Life thus no longer supported. Please upgrade your system as soon as possible.
