[juantxorena]

Describe the bug
After opening the app and selecting or trying to fetch data of something (film, serie, episode...), it crashes with a core dump

To Reproduce
Steps to reproduce the behavior:

1. Go to movies or tv shows
2. Click on any film or episode of a tv show
3. Eventually, the app will crash with a core dump

Expected behavior
It shouldn't crash

Screenshots
Here's a log with the error. In this case it crashed just by selecting the film to scrap:

MediaElch Version:

• 2.10.1-dev (nightly)
• 2.10.0 stable

Operating System:

• Windows
• macOS
• Linux (distribution: openSUSE Tumbleweed)

Additional context
My data is in a SMB share, and the app was installed via flatpak

[bugwelle]

Hi,

thanks for reporting. We don't provide Flatpak images out-of-the-box. Where did you install MediaElch from?
We also provide RPM packages for openSUSE.

Regards,
Andre

[juantxorena]

Sorry, I was mistaken, I don't have it installed via flatpak, but from an obs repo (bugwelle).

[bugwelle]

Ah, ok. Then I'll spin up my Tumbleweed VM in the next few days. This is reproducible, correct? I could be related to SMB, but I'm not sure. MediaElch should handle it correctly

[juantxorena]

The problem still persists, the app is completely non-usable. It used to work, it appeared in the last weeks, maybe some update?

Edit: I've just tried with another local directory instead of a SMB share, and it has the same problem.

[juantxorena]

Maybe I could add a core dump, to help with the debug:
core.MediaElch.1000.6e7ced27b13640e7a996f0a5b53162fd.27195.1681927759000000.zip

[bugwelle]

I reproduced the issue on my openSUSE Tumbleweed installation. Interestingly, not on my Ubuntu system. I'll have to see why that is.

[bugwelle]

The issue is with MediaInfo...

Ok. I'll have to check their changelog.

[bugwelle]

@juantxorena This is a bug in libmediainfo and nothing we can fix on our side. Please see MediaArea/MediaInfo#707 (comment) for details.

I installed their latest snapshot on my Tumbleweed installation and the crash is gone.

I would recommend to either try to reach the libmediainfo maintainer for openSUSE Tumbleweed¹ or wait a week or two. libmediainfo v21 works as well. You can also try to install the snapshot version mentioned in the issue, but be aware of possible conflicts.
