Qt: Session management error: Could not open network socket

[gheeshuggah]

I just installed flatpak and tried to run this scribus flatpak. I see the splash screen and then it crashes with this:

Qt: Session management error: Could not open network socket
QMetaObject::indexOfSignal: signal finished() from QThread redefined in ScDLThread
scribus: symbol lookup error: /app/lib/scribus/plugins//libscriptplugin.so: undefined symbol: PyUnicodeUCS2_SetDefaultEncoding

Flatpak 0.11.3
System: Kernel: 4.15.8-1-MANJARO x86_64 bits: 64 gcc: 7.3.0 Desktop: Xfce 4.12.4 (Gtk 2.24.31) Distro: Manjaro Linux

Did you build it yourself or use the repo version?

Try updating, I cannot reproduce this issue.

Does it happen with this version?
