kbuildsycoca5 crashing

[Jeremy Whiting]

I see. Some kde applications segfault (klettres, okular) other's run
ok (dolphin, khangman) I haven't tried others. As for qt binaries I
checked the binaries that come with the arch package, and assistant,
designer, qdbusviewer all work fine. Is there one in particular I
should check?
