This is my attempt to find out what is going on:

wolfgang at Fuji:/tmp$ ls lyx*
lyx_tmpdir.vblaVyVPIGKk:
Buffer_convertLyXFormatLIfocI.lyx  lyx_tmpbuf0  lyx_tmpbuf2
Buffer_convertLyXFormatYEHRwL.lyx  lyx_tmpbuf1  lyx_tmpbuf3

lyx_tmpdir.ZZlQmEsDQdUW:
lyxsocket  lyx_tmpbuf0  lyx_tmpbuf1
wolfgang at Fuji:/tmp$ ls lyx_tmpdir.AD* >>>1st one
ls: Zugriff auf 'lyx_tmpdir.AD*' nicht möglich: Datei oder Verzeichnis 
nicht gefunden
wolfgang at Fuji:/tmp$ ls lyx_tmpdir.cd*
ls: Zugriff auf 'lyx_tmpdir.cd*' nicht möglich: Datei oder Verzeichnis 
nicht gefunden
wolfgang at Fuji:/tmp$ ls lyx_tmpdir.vbl*
Buffer_convertLyXFormatLIfocI.lyx  lyx_tmpbuf0  lyx_tmpbuf2
Buffer_convertLyXFormatYEHRwL.lyx  lyx_tmpbuf1  lyx_tmpbuf3

Why are the buffer files of lyx shown, but tells they are not found?
The newest one is the first  (marked >>>1st one)kwrite
the older one are below it

If I click on the
Buffer_convertLyXFormatLIfocI.lyx  lyx_tmpbuf0  lyx_tmpbuf2
lyx opens but:

Das Dokument /tmp/lyx_tmpdir.vblaVyVPIGKk/master.lyx existiert noch nicht.

I can open it, however, with a text editor (kwrite)

All very strange and confusing for me.
