Can you please share the version of libreoffice you're using?

    apt policy libreoffice-core

Are there any crash files for libreoffice in /var/crash/ ? If so, can you please attach them here?

[Lyn Perrine (walterorlin)]

libreoffice-core:
  Installed: 1:5.4.4-0ubuntu5
  Candidate: 1:5.4.4-0ubuntu5
  Version table:
 *** 1:5.4.4-0ubuntu5 500
        500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

[Lyn Perrine (walterorlin)]

Doubt this is helpful but it was in /var/crash/

[Olivier Tilloy (osomon)]

That crash file is not relevant indeed.

Can you install debug symbols for libreoffice, then run libreoffice in gdb and see if you get a useful stacktrace?

See https://wiki.ubuntu.com/Debug%20Symbol%20Packages for how to install the debug packages, and then from a terminal run "gdb --args libreoffice --writer" and reproduce the crash. At the gdb prompt input "bt" to get a backtrace.

The same situation for me with:

libreoffice-core:
  Installed: 1:5.4.5-0ubuntu0.17.10.1
  Candidate: 1:5.4.5-0ubuntu0.17.10.1

        100 /var/lib/dpkg/status
     1:5.4.1-0ubuntu1 500

[Chris Taylor (chris-taylor-t)]

Temporary workaround is to modify setting in Tools -> Options -> LibreOffice -> General and Check 'Use LibreOffice dialogue boxes'. See https://bugs.documentfoundation.org/show_bug.cgi?id=98776

[TomaszChmielewski (mangoo-wpkg)]

Also affects me, using Kubuntu.

[Olivier Tilloy (osomon)]

I can reliably reproduce the issue after installing kubuntu. As suggested by Chris in comment #7, using custom dialog boxes works around the issue.

[Alexander Lochmann (alexander-lochmann)]

As I've already mentioned, one of my machines is also affected. I posted context information for that machine which is *not* affected: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1751783 .

Disabling the apparmor profiles makes the crash go away (being implemented to fix bug #1751005).

This looks related to https://cgit.freedesktop.org/libreoffice/core/commit/?id=b13678b1e1d6f4cac548ae7e088b6030c31cf081.

[Horst Schirmeier (horst)]

I can confirm that disabling the apparmor profiles (comment #12) makes the crash go away until next reboot:

  apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

[Olivier Tilloy (osomon)]

This bug was fixed in the package libreoffice - 1:5.4.5-0ubuntu0.17.10.4

---------------
libreoffice (1:5.4.5-0ubuntu0.17.10.4) artful; urgency=medium

  * debian/libreoffice-common.preinst.in: added to disable apparmor profiles on
    fresh installs and upgrades from 1:5.4.5-0ubuntu0.17.10.1 (LP: #1751005)

[Alexander Lochmann (alexander-lochmann)]

Do you seriously consider "added to disable apparmor profiles on" as a fix for this issue?
On my opinion, this is just a workaround.

[Olivier Tilloy (osomon)]

Copying here comment #51 from bug #1751005:

Apparmor profiles were not enabled before the 1:5.4.5-0ubuntu0.17.10.1 SRU.
The SRU accidentally enabled them and broke a flurry of use cases. That was a very bad regression.
The 1:5.4.5-0ubuntu0.17.10.4 SRU disabled them again. Regression fixed, hence the status.

We will work towards enabling apparmor profiles in a controlled manner.

[Alexander Lochmann (alexander-lochmann)]

Oh. If so, please excuse my harsh question.
I was not aware that apparmor profiles never been activated before for LO.

[m.eik michalke (m.eik)]

i ran into this with 1:6.0.7-0ubuntu0.18.04.7 and the aforementioned workaround still saved me. is this another regression?

[Alexander Adam (7ql6)]

I can confirm that this issue is still present in 1:6.0.7-0ubuntu0.18.04.10.

the command

  $ sudo apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

still works though.

[lukyluke (luca-tagliacozzo)]

As Alexander already said I confirm that in Kubuntu 18.04 and the following version is still there the output of apt policy libreoffice-core:

libreoffice-core:
  Installed: 1:6.0.7-0ubuntu0.18.04.10
  Candidate: 1:6.0.7-0ubuntu0.18.04.10
  Version table:
 *** 1:6.0.7-0ubuntu0.18.04.10 500
        500 http://es.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status
     1:6.0.3-0ubuntu1 500
        500 http://es.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

In my case the sudo apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

disprove the situation, since when I try to save a file, I get a lot of errors about not finding the apparmor profile and then whenever I try to type a name the first character I press gets repeated indefinitely and then Libreoffice crashes.
