Created attachment 159902 [details] Extract of syslog showing the stack trace cause by the SIGSEGV When editing a ODT document containing a picture (e.g. nextclouds own About.odt), selecting the tab Crop in the IMAGE popup window generates a SIGSEGV in loolwsd This could be related to Bug 106280 but this time it is in LibreOffice Online. I found the problem in my system consisting of NextCloud combined with Collabora Office CODE version. Steps to reproduce the behavior: Open About.odt select the picture in the document In the sidebar, in the part Position and Size, click the little square to get more options. The IMAGE popup window appears. All tabs, except the Crop tab can be selected and the corresponding options appear. When clicking the Crop tab, the IMAGE window disappears after 2 seconds Operating system: Linux Mint 19.3 Web server: Apache2 Database: SQLite PHP version: 7.2.24 Nextcloud version: 18.04 Version of the richdocuments app 3.5.3 Version of Collabora Online 4.2
