--- Comment #13 from Milian Wolff <mail@milianw.de> ---
OK, I finally figured out the reason for this bug, the fix is not yet clear to
me, lets see.

1) we create a QID and store its Indexed form in memory
2) since we never serialize this item it never plays a role in the on-disk
refcounting
3) on shutdown, globalItemRepositoryRegistry().finalCleanup() is called in
DUChain::shutdown
4) later in that function, sdDUChainPrivate->doMoreCleanup(); and
sdDUChainPrivate->clear(); are called, the latter of which will again call
doMoreCleanup
5) eventually in-memory DUContexts will get unloaded, if they happen to have an
IndexedQID stored which was cleaned up (since it never was serialized, its
refcount was not increased), we will access a deleted item in the itemrepo

-> havoc.
