Confirming this bug.
sounds like the override state is not taken into consideration for the decoration shown condition for tabbing, probably a dupe of bug #221868 i assume you can not reproduce it by using the context menu to just hide the decoration and (i.e. no chrome buttons either)? would you say this is the direct source of bug #222813 ?
I retested the grouping feature: If I disable the chromium deco (right click on chromium deco -> "Use title and border of system") then grouping is possible without kwin crashing. After that I can group/ungroup with or without chromium borders. Even right click on kde deco (see bug 222813) works (grouped and ungrouped). When kwin is restarted (kwin --replace&) then kwin crashes again if chromium deco is enabled and I try to group. Another strange behaviour: If chromium deco is enabled and chromium is grouped with another application, the kde deco vanishes when switching to chromium and reappears when switching away. This is probably another bug, because when grouping is enabled the kde deco is always enabled and I cannot disabled it (although I would like to).
confirmed. this and #222813 are slight different, but the common source seems to be that no ClientGroup is constructed when a decoration is shown for a former override window. ... so it's not even f*** chromes fault ;-) please notice that the tabbing is a) new b) quite tied to the decoration, so doing hackish things on decorations could be error prone (i.e. use with care)

Remarkable enough to add, kwin reborned without a click, quick and smooth. Not even used "restart app" from bug report window.
