The process crashes on "strlenW" (unicode.h), since a NULL pointer is passed
from "resolve_keypath" (called on "comp->FullKeypath = resolve_keypath(
package, comp );")

The NULL pointer comes from the following line in resolve_keypath:
key = MSI_RecordGetString(row, 3);

The record type is "MSIFIELD_NULL", but it should be "MSIFIELD_WSTR".
"MSI_RecordGetString" returns NULL since of that, and this NULL pointer is
passed to strlenW.
