I just finished a full debug build and there the things are crashing much less frequently. E.g. system settings and dolphin do not crash anymore (but the Desktop Activity Settings does) The tweaks done for the debug build could give us some clues I guess.
It is not a full full debug build, it's just the -g added, so there's still a lot of the optimizations in place. You can get it at http://solaris.bionicmutton.org:10010 but I warn you, it's bigger than usual. Just KDEgdm-integration is ~ 1.3 GB. Also KDEpim is not included due to an unresolved build issue. For unknown reason qt was not set as a dependency, it certainly did not get pulled automatically in my test install, so please don't forget to install it as well. -- This message posted from opensolaris.org
