Crash when loading large JPG

Crash when loading large JPG.

QPixmap p;
p.load("image.jpg");

Crash in

QPMCache::insert(const QString&, const QPixmap &, int)

when

QCache<QPixmapCache::Key, QPixmapCacheEntry>::insert

return false.

cacheKeys.remove(key);
releaseKey(cacheKey);

After removing key from the cacheKeys, the cacheKey calls deref and self destroys. releaseKey is call with already destroyed object.
Probably, releaseKey should be called before removing from the cacheKeys.
