tmp/lyx not a readable file

[Wolfgang Engelmann]

loading another file gives
/tmp/lyx_tmpdir.PrXtIVAGvvMT/Buffer_convertLyXFormatetZcbC.lyx ist kein 
lesbares LyX-Dokument.
Must inquire why. Perhaps remove the tmpdir?

> Must inquire why. Perhaps remove the tmpdir?
error occurs again after removing it and trying the lyx file again

The terminal message is
kf.kio.widgets.kdirmodel: No node found for item that was just removed: 
QUrl("file:///home/wolfgang/A-screenshot.png")
Warning: 609: Format not supported.
Warning: Quitting.
Error: Dokumentformat-Fehler

I found that the /tmp is

drwx------ 3 wolfgang wolfgang 4096  1. Mär 08:46 lyx_tmpdir.eHwFXSFnsYFN

so I chmod 01777 tmp

drwxrwxrwt  20 root root     20480  1. Mär 08:45 tmp

However, not all are behaving as requested:

-rw------- 1 wolfgang wolfgang   49  1. Mär 08:06 xauth-1000-_0

and so also the lyx:
drwx------ 2 wolfgang wolfgang 4096  1. Mär 08:51 lyx_tmpdir.EyjIjarOKRSY

However, an earlier lyx file which works, is also
drwx------

so that can't be the reason.

I noticed also, that in lyx only those files are shown under
File > Open Recent
which were created before the disaster.

Thanks for any hint

Wolfgang
