Subject: [PATCH] Add debug log for 5914560 and 6383850

This won't be shown in usual condition since in most cases the method
will just use the block just above the logging and return true/false
there. On the other hand this might be useful if the case is truely
exceptional and thus this path is really used.

Bug: 5914560
Bug: 6383850
