after deleting

.local/share/gnunet/fs/persistence/gnunet-fs-gtk/

it's not crashing anymore

Do you have a backup of that .local/share/gnunet/fs/persistence/gnunet-fs-gtk/
directory? That would be helpful to reproduce the issue. It looks like memory corruption, thus a trace with valgrind would have been very helpful...

After putting the folder back, it doesn't crash anymore.

Attached is the file .local/share/gnunet/fs/persistence/gnunet-fs-gtk/download-child/82JZ1b , this is after moving it, starting gnunet, and putting it back

So i'm not sure how to reproduce this, cause i didn't make a backup of that file.

Closing for now, let's hope somebody will eventually produce this in a way that can be reproduced (don't delete files...).
