segfault on Alpine Linux when loading secrets

[tml]

Describe the bug

During weechat startup, when prompted for the passphrase to decrypt secured data, I get a segfault as soon as I enter the correct passphrase.

Steps to reproduce

1. Have encrypted data
2. Start weechat
3. Enter passphrase at prompt and hit enter
4. Get segfault

Current behavior

Please enter your passphrase to decrypt the data secured by WeeChat:
(enter just one space to skip the passphrase, but this will DISABLE all secured data!)
(press ctrl-c to exit WeeChat now)

=> ********
Program received signal SIGSEGV, Segmentation fault.

Expected behavior

Weechat should not segfault

Suggested solutions

No response

Additional information

Please enter your passphrase to decrypt the data secured by WeeChat:
(enter just one space to skip the passphrase, but this will DISABLE all secured data!)
(press ctrl-c to exit WeeChat now)

Program received signal SIGSEGV, Segmentation fault.

Hi @tml,

It seems you have some Python scripts installed, can you please give me the list, so I can try on Alpine to reproduce the issue?

Thanks.

That's the thing, I don't actually have any python scripts installed.

According to your backtrace, Python is loading a script, can you check in ~/.local/share/weechat/python/ if you have some Python scripts? (scripts installed are not visible in configuration files)

Or try to run weechat -s, which runs WeeChat without loading any script. Does that help?
