[CRASH] Olive freezes and I have to force quit and this slows down my work

Platform Linux Manjaro

Summary it would seem that when the video is playing in the preview if I click with the mouse in a previous position of the clip then the program freezes and I have to force quit. I installed the AppImage version of Olive (maybe it may not be fully compatible with Manjaro)

Steps to Reproduce

1. Click space on the keyboard
2. While the track (vertical blue line) moves along the clip if I decide to select a previous minute (of the clip) then the Olive program freezes and I can't do anything but force quit

Crash Report

I ran the `xdg-open video.ove` command and got this output:

Additional Information I know I shouldn't be using Olive as my primary video editor but I really like the aesthetics and I wouldn't switch to another video editor just because it crashes every 5 minutes... hope that fixes the problem!

Same thing here

Same thing here

I tell you the truth I really like the layout received by Olive but unfortunately not having any response I adapted learning to use kdenlive which works really well. I still hope they will fix this in the recent future

I'm not able to reproduce this on Windows but looking at the output you got I think your audio may be set up wrong. If you go Tools -> Preferences -> Audio what settings are selcted there?

Hi, here's how the audio settings are set:

[ThomasWilshaw]

Could you try using a different back end? Also are you able to provide a full backtrace/ run through a debugger?

[AntonioBerna]

Couuld you try using a different back end? ALso are you able to provide a full backtrace/ run through a debugger?

If you explain to me how to do it I can try

[ThomasWilshaw]

In the Audio Settings dialoge you screen shotted above there is a drop down called Backend at the top, can you change that? I donlt know if this will fix it but it's worth a shot

Same thing happens to me on Kubuntu. Sometimes it works flawlessly but sometimes it freezes. Also using the appimage
