Error messages with lyx2.3

[Kornel Benko]

I got 10 messages of the form:
Traceback (most recent call last):
  File "/usr/local/share/lyx2.3/scripts/convertDefault.py", line 73, in <module>
    if (im or gm) and os.system(r'%s %s "%s" "%s"' % (command, opts, 
sys.argv[2], sys.argv[3] + ':' + sys.argv[4])) != 0:
IndexError: list index out of range

but cannot reproduce anymore. What I had done:

1.) Compiled and installed lyx2.3
2.) run lyx2.3 --> 
        ...
        +checking for package biblatex [biblatex]... yes
        ...
3.) change to use oxygen
4.) close lyx2.3, restart
5.) open lib/doc/attic/eu_UserGuide.lyx
6.) Select TOC with graphics
7.) Look at different parts of the document
8.) exit
Somewhere between 5.) and 8.) the messages appeared. I saw them only after I 
closed lyx.
