Review request for kdelibs.


Summary
-------

Attached patch fixes a crash reported by gopalK, one of our Calligra at Windows heros.

Backtrace (only one line);
#0  KDirLister::Private::emitChanges (this=0x13332c70)
at d:\kderoot\git\kdelibs\kio\kio\kdirlister.cpp:2155

The reason is that kDirListerCache->itemsForDir can return NULL. That is handled in all cases in that file except those two lines. The patch fixes it.

p.s. whoever pressed "Ship It" please commit the patch for me and backport cause I didn't had the time to get my kdelibs+kdebase setup updated since the latest moves and renames. Thanks in advance :)
