GLib-GIO-ERROR on FileChooser

[ProfDavidMora]

Hi, thanks for your software.
I have encountered a problem when opening files on 6.0.5.1 (installed as a snap on Debian 10 and testing on 11). It crashes when clicking on "Open Media". Using --debug it shows error
(python3:6120): GLib-GIO-ERROR **: 11:16:59.481: No GSettings schemas are installed on the system

There are a bunch of schemas available as confirmed with gsettings list-schemas. Tried with some environment variables as noted in several places along the Internet (we all know I'm talking about SO):
export XDG_DATA_DIRS=/usr/share:~/.local/share/:/usr/share/glib-2.0/schemas/
but it didn't resolve the situation. I also reinstalled gsettings-desktop-schemas and removed/reinstalled the snap (without and with purge option).

Dragging and dropping the file gives a different Python error:

Windows version works fine, and I can work the files there, though my main computer is the Linux and I'd like to be able to use it again (it used to work, but I don't recall the version I had before an upgrade that is, possibly, the culprit).

Hope I provided good enough info to start working on this. Let me know what else can I try, I appreciate your looking at the situation.

Thx for all the feedback. I'm aware of this issue re Snap but cannot replicate it on my Ubuntu/Debian installs. Hopefully resolved soon.

You can install proper app version via Ubuntu PPA directly, avoiding Snap issues:

$ sudo add-apt-repository ppa:ozmartian/apps
$ sudo apt-get update
$ sudo apt install vidcutter

Many thanks for checking in. If I can be of any assistance, let me know, I know a thing of two about programming. I can share my setup with you for a while or anything that might help if you want to take that approach. I'll use the software on Windows while it gets fixed.

The issue is Snap specific, not VidCutter itself. I'm sure the Snap works if you open a video file via drag & drop from file manager or "Open With" option in file manager right-click menu. Give that a test, should work. Thx!

[ProfDavidMora]

The offer still stands, if there is anything you want to try; if there is nothing specific to be done, that's what it is.

I did mention drag and drop with the Python error in the initial post, it is not working either. I just tried the context menu, but nothing happened; then I tried command line and it showed the same Python error.

$ vidcutter --debug FileName.mkv

The program is used exclusively with MKV files recorded with OBS, if it matters for anything. Thanks a bunch again.

On ubuntu 20.04, "Drag and drop" or "open with" options load video. I can create/remove/rearrange clips but as soon as I click the save media button it crashes. The terminal output is give below:

This has been fixed with the latest snap released a few mins ago.

This is still an issue for me unfortunately
