Created attachment 156972 [details] bt with debug symbols (gtk3) On pc Debian x86-64 with master sources updated today, I could reproduce this.
Regression from: https://cgit.freedesktop.org/libreoffice/core/commit/?id=9667a8ab1c4809c75f6258a8739b9036c86b2a37 tdf#129517 add "Preview" labels in BulletandNumberingStyle dialog box - on Position tab - on Customize tab Reverting this commit locally prevents my build from crashing. This log seems to indicate the issue: (soffice:625862): Gtk-WARNING **: 21:15:18.179: 'label' is not a valid child type of 'GtkBox'

Mild hypothesis: <object class="GtkFrame"> needs to be added wrap both the preview window and the label (in both numberingposition.ui and numberingoption.ui) <object class="GtkFrame"> <child type="label"> <object class="GtkLabel" id="frame-label"/> </child> <child> <object class="GtkEntry" id="frame-content"/> </child> </object>

This GtkBox for numberingposition.ui will be <object class="GtkBox" id="box1"> and it is true that GtkBox does not have label as a child type.
