I can't reproduce it in

or gtk3.

Could you please try to reset your Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and re-test?

Same result, crash in the moment. It also happens with other floating panels like properties.

I can't reproduce the crash with 5.2.6.2 / Ubuntu 16.04, either.

Xisco, did you manage to dock the pane again in 5.4 master build? (offtopic)

Yes, no problem here.

@Eugenio, could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongsidethe standard version.

Notice that Wayland is being used by the reporter.

Eugenio: if you can get this build to work with Arch Linux, you could get a debug trace of the crash: http://dev-builds.libreoffice.org/daily/master/Linux-rpm_deb-x86@71-TDF-dbg/current/

https://wiki.documentfoundation.org/QA/BugReport/Debug_Information#GNU.2FLinux:_How_to_get_a_backtrace

Ok, Downloading x64_64 version, if this is OK for you.

I can't start a X graphical session at this moment, but I will try to do ASAP :)

Thanks for your help!

If you mean this, OK: http://dev-builds.libreoffice.org/daily/master/Linux-rpm_deb-x86_64@70-TDF-dbg/current/

..but that is over a week older than the build from tinderbox 71. Also, make sure you get the -dbg build, so you can get a trace with useful information.

Ok then, I will post both results

> Ok then, I will post both results

Ok, here they goes:
- 5.3.0.3 (libreoffice-fresh package in arch linux): I can't even remove the slides panel, so I can't test the failure!
- Daily@70: The error is gone.

Tried to find the "still" version with debug symbols with no luck.

Do you want me to try further the still version, in order to fix the bug in that version?

Unfortunately Arch Linux does not package the debug symbols. Ubuntu and some other distros do.

Just to check, you could try running the daily build from the command line with

SAL_USE_VCLPLUGIN=gtk3 soffice

and then look into the Help - About that the VCL is gtk3 like so:

CPU Threads: 8; OS Version: Linux 4.10; UI Render: default; VCL: gtk3; Layout Engine: new; 

If it still does not crash, it seems the problem was fixed after the 5.3 release.

If I run that way, it still say "VCL: gtk2":

$ env SAL_USE_VCLPLUGIN=gtk3 ./soffice

Urgh.. I am just assuming your crashing 5.2 was using gtk3 as you use GNOME.

Btw. I was able to undock the slides panel in 5.3 in Arch Linux with gtk3, but I can't get it to dock back!! No crash, though.

If you have a fast machine with lots of RAM, you could try doing your own build.

I just updated the build dependencies for master (5.4) to the wiki:
https://wiki.documentfoundation.org/Development/Linux_Build_Dependencies#Arch_Linux

(Only difference to the 5.3 deps is that glew changed to libepoxy)

Here are the cloning a building instructions: https://wiki.documentfoundation.org/Development/BuildingOnLinux#Cloning_and_building

The only change in your case would be:
./autogen.sh --enable-symbols

That enables the debug symbols.

gtk3 support is built by default. You can always verify from the Help - About screen.

I haven't that machine :) I was expecting to be able to access to `still` debug version, if you are still interested in fix the `still` version.

I found gtk3 version runs smoother than gtk2 in my machine, I suppose that is consequence of not to have two different libraries loaded at the same time.

Arch Linux does not package debug symbols, so the only way is to build LibreOffice from source. It would be different, if you used Ubuntu or some other distro that packages debug symbols.

Hi, @Xisco, sorry for the late response.

With impress version 5.4.2.2.0 (the latest packed with arch linux), I'm unable to unlock panels anymore, so I can't try to reproduce the bug. If it's the expected behavior, it's ok to close the issue for me.

No, it's not the expected behavior.

The crash is also reported in Bug 103510, and the inability to undock the panel in recent versions is the expected behavior under Wayland.
