           Summary: ApplicationCacheStorage::storeNewestCache() Crash

          Priority: P2

Right now in ApplicationCacheStorage.cpp when openDatabase(true) is called it always assume it will succeed, but it could fail, for example when appcache storage is set to a storage card and the storage card is now unplugged.

Plan to add m_database.isOpen() check after every openDatabase(true) call.
