libreoffice crashes immediately after start

[Henning Geinitz]

I try to run libreoffice e.g. from konsole by entering "libreoffice". Immediately after shortly showing the logo the "Libreoffice Document Recovery" windows pops up explaining that lo crashed due to an unexpected error. In some cases the window is shown even twice.
When I click "ok" lo restarts and shows the same window(s). When closing the window, lo closes also.
I already purged and reinstalled all lo packages and removed ~/.config/libreoffice.
If I remove "libreoffice-kde" and "libreoffice-gtk*" packages, lo will start without a crash. However, in this case no printers are found.

libreoffice --backtrace output is attached.

Crash appears since a few weeks. However, I can't find out which update or other change could have caused this.

Thanks for the report Henning.
Would you mind testing libreoffice 1:6.0.6-0ubuntu0.18.04.1 from bionic-proposed (see https://wiki.ubuntu.com/Testing/EnableProposed)? Please comment here to let me know whether the issue is still there.
