Mh, don't see the connection to the duplicate. 
In any case, I (orig. poster) also have sometimes the situation that krunner runs "amok", with full load on one core, for hours. krunner kill and restart helps.
May be related to the problem, or not.

May have to do with a few hundred repetitions of the entries
"kglobalaccel(5662) GlobalShortcutsRegistry::unregisterKey: Unregistering key ..."
and
"kglobalaccel(5662) GlobalShortcutsRegistry::registerKey: Registering key ..."
for all krunner hotkeys ...

Code in kdirlister.cpp:527:
    if ( item->complete ) {

item is assigned a few lines above:
    DirItem *item = itemsInUse.value(urlStr);
    Q_ASSERT(item);
....

seems the Q_ASSERT should be extended to check item against NULL in release code, also.
