Description Thomas Hackert 2016-10-24 08:52:42 UTC
Hello @ll,
I hope I have chosen the right component and such. If not, feel free to change adequately ... ;)

Steps to reproduce:
1. Start LO
2. Press <Alt>+<M> to start Math
3. Rightclick in the bottom part of the window (Command pane? Or how is this called in English?)
4. Leftclick there

On my system

OS: Debian Testing AMD64
LO: Version: 5.3.0.0.alpha1
Build ID: f4ca1573fcf445164c068c1046ab5d084e1b005f
CPU Threads: 4; OS Version: Linux 4.5; UI Render: default; VCL: gtk2; 
Locale: de-DE (de_DE.UTF-8); Calc: group

LO crashes immediately ... :(
Sorry for the inconvenience
Thomas.
Comment 1 Thomas Hackert 2016-10-24 09:11:59 UTC
Hi again,
needed to switch my systems, as I can also confirm it on

OS: Debian Testing i686
LO: Version: 5.3.0.0.alpha1
Build ID: f4ca1573fcf445164c068c1046ab5d084e1b005f
CPU Threads: 2; OS Version: Linux 4.7; UI Render: default; VCL: kde4; 
Locale: de-DE (de_DE.UTF-8); Calc: group

On both systems, I followed the instructions from https://wiki.documentfoundation.org/Installing_in_parallel/Linux to install LO alongside to Debian's version.

The interesting difference is, that on my i686 system I am using KDE whereas on my AMD64 system XFCE 4. After the crash on my i686 box, I get a message about a KWin crash. But neither "soffice -backtrace" nor "soffice -strace" produces any file to attach to this bug, sorry ... :( .xsessions-errors shows only

Just start LO Math however you want
mouse in the pane for the formula statement
the context menue appears, click left mouse
button without choosing an entrypoint in tne
context menu immediatly crashs LO

crash details: a980cfba-025c-4511-9b2f-2f31647dbe78

Thanks Thomas,

Comment 3 Thomas Hackert 2016-10-24 12:28:41 UTC
Hello Lothar, *,
as you have confirmed it with Win as well, setting "Hardware" to "All" instead of "Linux" ... ;)
Thanks for confirming and have a nice day
Thomas.
Comment 4 riesslibo 2016-10-24 12:40:22 UTC
You are absolutly rhight, so it should be also changed in the title of the bug ;-) I will remove the "Debian" hint in the headline, hope you are ok with it.
Best
Lothar
