If you open the properties of an ODF document in the Finder (Cmd-I) what is the default app that is associated with that file ?

FWIW, someone had reported something similar with either the master build from the code repository, or a 6.0 pre-release, I just need to check.

@Albert : where are these blank icons shown ?

1) In the general Finder ?
2) In the LO open file dialog ?
3) In the LO StartCenter ?

Please provide a screenshot.

Hi,
I’ll try to answer all three comments

#1:
the associated app is (as it should) LO. 

#2:
I did the download from the LO download page - as well as the language pack.

#3:
1) yes
2) yes
3) no

I hope, the information helps a bit,

@Albert : thanks, very helpful.

Unfortunately, I can't reproduce this with :

Version: 6.0.0.3
Build ID: 64a0f66915f38c6217de274f0aa8e15618924765
Threads CPU : 8; OS : Mac OS X 10.13.3; UI Render : par défaut; 
Locale : fr-FR (fr_FR.UTF-8); Calc: group

All the document icons look normal to me on my system, even including the miniaturized preview.

Possibly, the DE langpack might be the problem...

I tried to install LO on an other machine, this time without language pack. The result was the same. Only that I had a closer look: the icons disappeared after I opened and saved the first file, exactly I opened and changed an .odt file. After saving the file all LO icons were blank; by opening a larger folder I could see that the icons were present in the first moment and then changed to blank (independently of the file type, .ods, odg, and .odp as well.

About dialog:
Version: 6.0.0.3
Build ID: 64a0f66915f38c6217de274f0aa8e15618924765
CPU threads: 8; OS: Mac OS X 10.13.3; UI render: default; 
Locale: de-DE (de_DE.UTF-8); Calc: group

So it seems not to be a problem of the language pack.

Did you try a safe boot (after closing all apps) and then rebooting normally?  I don't know if that would fix your problem, but it did fix a similar problem I had when replacing NeoOffice with LibreOffice.  The problem apparently is that some file associations are kept in caches that don't get cleared or updated.  Safe boot apparently clears a lot of caches.  (safe boot: press and hold shift after the chime until the apple logo comes up.  You will probably have to log in twice. "safe boot" or "safe mode" -- I forget which -- will be displayed in red in the menu bar. Don't be worried:  it takes a lot longer than a normal boot.)

@Albert : which app is associated with the ODF file types ?

When you select a file and use Cmd-I, what is the default application shown in the  properties dialog of the file ?

If it isn't the latest version of LibreOffice (currently LO 6.0.1.1), then is the problem resolved when you re-associate all files of that type to the correct version of LO ?

Response to comment 10
I tried to clear the caches; in the web I found a hint to first replace and then delete the icon of the app itself - this helped for 6.0.0.3. Some days later I installed 6.0.1.1 - the icons disappeared again, but this time nothing would help. But after I installed the supplemental system update for mcOS 10.13.3, all icons reappeared.

This looks pretty like a caching problem, but I cannot say the reason for it.

Response to comment 11

when reporting the bug it was 6.0.0.3, now it is 6.0.1.1 - no older version involved. I have - for historical reasons OpenOffice installed as well. I tried to set OO as default app and then switched back to LO, but that did not have any effect. 

For information - the effect was exactly the same on my laptop as well as on the desktop machine.

Judging by comment #11 this was not a bug in LO, but a caching problem?

Setting as resolved - not a bug
