Roman/Alex: could one of you give it a try?

I have similar system.log entries as Jim. Here is what mdworker is reporting for me:

---------------------------------------------------

thank you Petri for your feedback. Since you're the second one to have this, put it at NEW.

Thorsten: macos specific, one for you?

Perhaps a start to investigate:
https://developer.apple.com/library/mac/#documentation/Carbon/Conceptual/MDImporters/MDImporters.html

I think Tor looked into that recently?

Yep, this should be fixed in 4.0.1.

There were two separate problems:

1) The importer (which is a dynamic library even if its name doesn't end in .dylib) didn't export the symbol MetadataImporterPluginFactory, as seen in the message in comment #2.

2) The code in the importer (which, perhaps sadly, handles only ODF documents) didn't parse the outer ZIP archive structure of ODF documents properly; this was evident only after problem 1 was fixed.

"should" as in "hopefully is"

Then let's state it as such - 4.0.1 rc2 due end of the week for verification, thx Tor for addressing it!

Spotlight still not working... Regression?

MacBook Pro 13-inch, Mid 2012 intel.
OS X 10.8.5 (12F45) 'Mountain Lion'.
LibreOffice Version: 4.2.0.4 Clean install.
Build ID: 05dceb5d363845f2cf968344d7adab8dcfb2ba71

Files are not indexed / searchable with Spotlight. Running mdimport manually seems to fail silently. Checking logs reveals:

After one year and a half, any update with last stable LO version 5.0.3?
Indeed, there's now only 64bits LO for MacOs.
Of course, for the test please rename your LO directory profile (see https://wiki.documentfoundation.org/UserProfile#Mac_OS_X)

Test on OSX 10.11.2

So, seems to work here, or have I misunderstood something ?

Alex:pb is in Lion Mountain/10.8. Since min prerequisite for LO is 10.8, it may be still relevant.
