Scribus crashes when import big files

[elm31rugby]

Hello, and sorry for my english (I'm French !)
Using Ubuntu 20.04, Scribus 1.5.5
I'm editing books, so I need to import "big files" in Scribus
My file is about 60 pages A4. It is a text file, I just import text.
When I try to save my Scribus File, it crashes
To know what happens, I lanch Scribus in a shell, and the shell returns :

Code Select Expand

Impossible de trouver le symbole (/usr/lib/scribus/plugins//gettext//libtxtim.so: undefined symbol: GetText2)

I've been looking for a solution on Ubuntu french forum, but no way to solve it.
Have you any idea ?
Thank you, have a nice day !
