This bug was filed from the crash reporting server and is br-dd72c410-b876-4b63-8893-d932db81c5fa.
=========================================

Open a blank LibreOffice Draw document.
Open the "Text Formatting" toolbar. Be sure it is positioned such that the "Line Spacing" tool is not displayed, but must be accessed via the expansion arrows on the left side of the toolbar.
Expand the toolbar using the expansion arrows and select the "Line Spacing" tool.
Crash.

Hello,
thanks for reporting.
I can reproduce it in

Version: 5.3.0.3
Build ID: 1:5.3.0~rc3-0ubuntu1~yakkety1.1
CPU Threads: 4; OS Version: Linux 4.8; UI Render: default; VCL: gtk3; Layout Engine: new; 
Locale: es-ES (ca_ES.UTF-8); Calc: group

but not in 

Version: 5.4.0.0.alpha0+
Build ID: d3b5bd4a07a619db6bee1c39c32280ac3c620532
CPU threads: 4; OS: Linux 4.8; UI render: default; VCL: gtk3; 
Locale: ca-ES (ca_ES.UTF-8); Calc: group

so it has been fixed in the meantime. Closing as RESOLVED WORKSFORME

*** Bug 104266 has been marked as a duplicate of this bug. ***
Comment 3 Aron Budea 2017-03-15 21:45:23 UTC
The fixing commit is below. However, it's not a good backport candidate as stated by Maxim in [1]. This has to be fixed differently in 5.3, thus resetting status to NEW.

Maxim, do you think there could be a quick fix to this crash in 5.3?

Comment 4 Xisco Faulí 2017-03-15 22:21:59 UTC
Hi Aron,
Thanks you for bisecting the fix.
It seems the crash was introduced when the toolbar was reworked in commit d38f7b74daf91ad47557bf8eca8946fd0ad97cf8. Adding Caolán as well to see if it can be easily fixed and backported.
Comment 5 Maxim Monastirsky 2017-03-15 23:46:56 UTC
This is not fixed in master, e.g right click the toolbar and choose "Line Spacing", or run this BASIC macro:

dim document   as object
dim dispatcher as object
document   = ThisComponent.CurrentController.Frame
dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
dispatcher.executeDispatch(document, ".uno:LineSpacing", "", 0, Array())

Similarly this can't be a regression from the toolbar changes, because one could customize the toolbar or run the BASIC macro before that too.

In addition, SfxItemSet::Get crashes can happen in many places in the codebase, and for completely different reasons. So Bug 104266 is unrelated to this one, and should be reopened.
