I cannot reproduce here with exactly the same build and a clean user profile (nor with a custom master build):

@Xisco: Do you have any additional extensions installed besides the ones bundled with LibreOffice? I just have those, s. attached screenshot.

it seems I have the same extension with the same versions as you...
Comment 4 Xisco Faulí 2018-11-20 16:20:18 UTC
I'm using Kubuntu 18.04.1

For the record, it hangs with GTK3.
@Michael, it works fine with GTK3 in your end ?

I'm using Debian testing with Plasma.
When using GTK3, it hangs for me as well.

On pc Debian x86-64 with master sources updated today + kde5 rendering, I got no hang but noticed these kind of trace on console:
warn:vcl.schedule:8331:8331:vcl/source/app/scheduler.cxx:367: we're too early - restart the timer (14ms)!
warn:svtools:8331:8331:vcl/source/graphic/UnoGraphicProvider.cxx:433: Could not create graphic: 0x8201(Error Area:Vcl Class:General Code:1)
QObject::startTimer: Timers cannot be started from another thread
QObject::killTimer: Timers cannot be stopped from another thread

I don't have these with gtk3 rendering.

I'm unable to reproduce this crash with Qt 5.11.3, but I didn't try Qt 5.9.x. Can someone confirm if it doesn't crash with Qt >= 5.11?

Yes, my result in comment 1 also was with Qt 5.11.x

... but of course I can't say that a newer Qt version will fix it for those that have the crash...

Peeps please try again, lot of threading fixes were merged recently and the backtrace looks very much like a threading/locking issue

This week some KDE5 commits were backported to 6-2 but not to 6-2-2. Probably one of those commits fixed the issue.
Closing as RESOLVED WORKSFORME
@Bubli, @Michael, thanks for your work here

Hm, so we might want to backport the threading fixes we made bc of crashers in tdf#119856

As far as I understand, those should be unrelated, since comment 15 mentions it's no more reproducible with 6.2.3.0.0+, and the fixes have not been backported to libreoffice-6-2 so far.
Comment 21 Xisco Faulí 2019-03-14 09:28:32 UTC

> Maybe bug 123745 ?

Sounds quite possible. In that case, there's nothing to do, since the patch has been backported to libreoffice-6-2-2 already. (I quickly verified that the commit wasn't yet included in Vera's 6.2.2 build from comment 15, but was in the 6.2.3 build).

I guess it can be quickly check with a local build in KDE5 by reverting it... I don't have it though

Unfortunately, I cannot test either, since I was never able to reproduce (s. comment 1).
Alternatively, it could be checked it's actually fixed with a recent build from the 6-2-2 branch. Or one could fall back to hoping it's fixed and in case that fails, it's still going to be fixed in 6.2.3 at least...
