Description unfa 2018-05-03 14:21:01 UTC

I've tried using the 18.4.0 AppImage from the official website.

When I run it, it seems to work fine , but then I click in the timeline it stops responding at all. It doesn't crash though, I have to manually kill it.

I've run it in gdb, here's the output:

(process:28117): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/app././/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory

When I've run it without gdb the last message in the terminal was always something similar to this:

I've realized that this also affected older Kdenlive version I have installed, and after reboot the problem went away.

Comment 2 Andrew 2018-06-12 01:17:07 UTC

I constantly encounter similar result (KDE UI freezes but not crashes) and can easily reproduce it on Fedora 27 WS. I run kdenlive v.18.04.2 via Flatpak with the user permissions (not sure if it makes a difference though).

Steps to reproduce:
- launch kdenlive
- click on the "New" icon to create a new project
- check box "Custom project folder"
- type in a path to some existing directory under $HOME
- click Ok to close Project Settings window
- menu File > Save As > Navigate to the custom project directory, give a name for the project
- click "Open"
- select Add Title Clip
- add some text inside the title clip
- click on the "Save As" icon
UI freezes forever.

Please try with the actual Kdenlive AppImage version 18.12.0b
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage
