kwrite/kate - why is 3.5.12 not affected (help analyzing)

Tim, All,

As I work to downgrade my R14 test boxes to troubleshoot what caused the kate/kwrite crash, I ran into a question I would like to get your thoughts on. All my day-to-day boxes run fully updated Archlinux (with one openSuSE box), and TDE 3.5.12 as the desktop (3.5.10 on SuSE).

QUESTION:

If the crash is due to an Arch update -- "They why do kate/kwrite continue to function normally in 3.5.12?"

It just strikes me that 3.5.12 would be much more susceptible to break due to Arch updates that R14. Would we not expect to see this same crash in 3.5.12 if this was due to an Arch update?

What say the experts? If this was Arch, wouldn't 3.5.12 have broken too?
