Bug#810124: digikam: Does not show albums until kbuildsycoca is manually called

[Steve M. Robbins]

Hi,

I recently picked up maintenance of digikam and haven't finished ramping up on 
KDE internals...

I received the following bug report.  I haven't noticed this problem myself, 
so it makes me wonder:

1. When, typically, is kbuildsyscoca run?  The man page and google were 
unhelpful so far.

2. Is it true that "other Debian KDE packages" run kbuildsyscocoa4 --
noincremental on installation?

Thanks,
-Steve
