Preview fails to launch Celluloid when using the official 3.0.1 AppImage on LMDE 7

[falcogiallo]

Hello,

I found an issue with the Preview feature while testing the official aMule 3.0.1 AppImage.

Environment

• aMule version: 3.0.1 (official AppImage)

• Distribution: LMDE 7 (Linux Mint Debian Edition)

• Architecture: x86_64

• External player configured in Preferences:

  /usr/bin/celluloid
  

Steps to reproduce

1. Launch the official aMule 3.0.1 AppImage.
2. Start downloading a video.
3. Right-click the download and choose Preview.

Expected behavior

Celluloid should open and play the preview of the partially downloaded file.

Actual behavior

Nothing appears on screen because Celluloid immediately exits.

When aMule is started from a terminal, the following message is printed exactly when Preview is selected:

/usr/bin/celluloid: symbol lookup error: /lib/x86_64-linux-gnu/libcurl-gnutls.so.4: undefined symbol: nghttp2_option_set_no_rfc9113_leading_and_trailing_ws_validation

Additional information

Celluloid itself works correctly when launched directly from a terminal:

/usr/bin/celluloid

It starts normally.

The error only occurs when Celluloid is launched through the Preview feature of the aMule 3.0.1 AppImage.

I have not investigated whether the issue is caused by the AppImage environment or by another interaction with the system libraries. I am only reporting the observed behavior in case it helps identify a bug or an AppImage compatibility issue.

If additional logs or tests would be helpful, I'd be happy to provide them.

Additional information: I realized I forgot to mention one detail. On the same system, using the distribution package of aMule 2.3.3 with the same configuration and the same /usr/bin/celluloid executable, the Preview feature works correctly.
The issue only occurs with the official 3.0.1 AppImage.

Hi falcogiallo,

This looks like a bug, so it should be reported on the "issues" section so we can deal with it properly. Please open the issue here:
