soffice.bin: Unknown event notification ; Syscall points to uninitialised byte(s) Libreoffice-core should 'recommend' "libreoffice-gnome | libreoffice-kde" installation

[dino99]

Using calc on yakkety 64 bits, within a gnome-shell session

Journalctl is spammed with lot of:
Aug 26 14:14:17 u64 soffice.bin[10208]: Unknown event notification 34
Aug 26 14:14:17 u64 soffice.bin[10208]: Unknown event notification 35
Aug 26 14:14:43 u64 soffice.bin[10208]: Unknown event notification 36
Aug 26 14:14:17 u64 soffice.bin[10208]: Unknown event notification 37

i does not know what that means, but working on a 450 kB ods file, when hitting the 'sort' icon applied to a 20 rows x 70 columns selected area with numbers and formulas (its an example; all other selection are also affected), for about 1 or 2 seconds the sheet become greyed before the 'sort' dialog box finally appear.

An other case inside Calc:
- select a cell (numeric one in this test)
- right click to select 'format cell'
- as a result, the system is unresponsive during a couple of seconds, cpu raise up to 100%, and finaly the options box appear

a backtrace also show (when calling the 'format cells' function):

Reading symbols from /usr/lib/libreoffice/program/soffice.bin...Reading symbols from /usr/lib/debug//usr/lib/libreoffice/program/soffice.bin...done.
done.
log will be saved as gdbtrace.log, this will take some time, patience...

** (soffice:5234): WARNING **: Unknown event notification 36
W: Unknown node under /registry/extlang: deprecated

W: Unknown node under /registry/grandfathered: comments

Such error cases is about opening the called box. Does that means a dependency is missing ? Journalctl is flooded by these 'unknown event'

This looks abnormal, and is very scarying as you wonder if you will loose your work due to a crash.

backtrace

Valgrind shows some important problems:
- Syscall param writev(vector[...]) points to uninitialised byte(s)
- Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)

New test with libreoffice (1:5.2.1~rc2-0ubuntu1) yakkety
but still the same problems
this is from a terminal: only load soffice, select an ods calc file to open it, but nothing done on that file, then closing it.

[dino99 (9d9)]

Tested the 5.2.2 version from the prereleases ppa: the problem reported here is still not fixed.
The log shows the libreoffice calc loading and then its closing.

Looks like that productivity app is missing real support: still no dev around yet

Wonder if the reported issue result of a compilation error:

After some digging, i've found that installing libreoffice-core (in case of non wanting to install the metapackage 'libreoffice') does not 'recommend' to install "libreoffice-gnome | libreoffice-kde" as it needs.

Please add "libreoffice-gnome | libreoffice-kde" as a libreoffice-core recommended dependency.

Actually i've upgaded to 5.2.3 rc1 & installed libreoffice-gnome , and the previous are gone

More recent version (5.3.2) has solved that freezing issue.
