the help button

When I touch the help-button in the presenter console LO crashes a) immediately and b) always.
I use LO 5.4.1 on kde neon plasma 5.10.5

I could not test with other configurations.

Oh that is clever! I will try in 6.0 too. But it's not super easy to get the second monitor. I will let you know!

LO left a "crash report" crashreport.libreoffice.org/stats/crash_details/a0d48498-8753-41b0-add2-42892c82f70
Is this on my local machine?

Comment 6 Caolán McNamara 2017-09-15 15:14:22 UTC
I can reproduce this in 5.3. The font ascent is 0 so there's a divide by zero. I suspect from the ascent issue that this may be related to bug 107249 and might be fixed as a side effect of that too.
Comment 7 pieter kristensen 2017-09-15 15:20:36 UTC
I don't understand at all what you say but it sounds promissing.
Keep up the good work!
