Creating a new calc document but this occurs with other type of documents.

Here a python script adapted from TableSample.py from 
https://wiki.openoffice.org/wiki/PyUNO_samples
(file attached)

===============================================================

import uno

from com.sun.star.text.ControlCharacter import PARAGRAPH_BREAK
from com.sun.star.text.TextContentAnchorType import AS_CHARACTER
from com.sun.star.awt import Size

from com.sun.star.lang import XMain

LIBREOFFICE_HOST, LIBREOFFICE_PORT = "127.0.0.1", "8101"


def createTable():
     ctx = uno.getComponentContext()

     resolver = ctx.ServiceManager.createInstanceWithContext(
                             "com.sun.star.bridge.UnoUrlResolver", ctx)
     connection = 
f"socket,host={LIBREOFFICE_HOST},port={LIBREOFFICE_PORT};urp"
     try:
         service_manager = 
resolver.resolve(f"uno:{connection};StarOffice.ServiceManager")
     except:
         print("connection error")
         return

     remote_context = service_manager.getPropertyValue("DefaultContext")
     desktop = service_manager.createInstanceWithContext(
                                     "com.sun.star.frame.Desktop", 
remote_context)
     for app in [
             "schart",
             "swriter",
             #"scalc",
             #"sdraw",
             #"smath",
             #"simpress",
             ]:
         print(f"Try {app}")
         doc = 
desktop.loadComponentFromURL(f"private:factory/{app}","_blank", 0, ())
         print("OK")


createTable()

The libreoffice service is launched with:

/usr/bin/libreoffice --headless \
     --accept=socket,host=127.0.0.1,port=8101;urp; \
     --nodefault --nofirststartwizard --nolockcheck \
     --nologo --norestore \
     --pidfile=/var/run/libreoffice.pid

The script can create "schart" and "swriter" documents.
Crash of the LO service with "scalc", "sdraw", "smath", "simpress" 
(commented on the script).

I have experienced other strange bugs and it seems that the LO API is 
pretty fragile. Sadly it does not surprise me... :/

Idealy it should be fixed upstream...

My bad, I used reportbug on the wrong terminal...
