Apache OpenOffice (AOO) Bugzilla – Issue 50836
Assertion "Don't close the medium when loading documents!"

The mentioned assertion occurs when loading Excel documents in read-only mode. MBA thinks that the function that looks for macros in the documents (to show the warning box) is the reason for the assertion.
Reset assigne to the default "issues@openoffice.apache.org".
