Not here - actually nothing happens (I blame the SC4/KF5 crossmix to fail on "KToolInvocation::kdeinitExec()" to resolve "kwin_rules_dialog" rules.cpp:991 RuleBook::edit(Client* c, bool whole_app) can you check whether it blocks in "save();" or in KToolInvocation? Latter is unlikely (should be fire and forget) and former would point the "everything freezes on KConfig invocation due to garbled cache files", but needs further investication (and is not blocking here for sure) neither here - I don't get a freeze, neither the dialog ad just a crash of kdeinit5 with useless backtrace. I can confirm the crash not the freeze I also can only confirm the crash not the freeze. // Application: kdeinit5 (kdeinit5), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
