FIXED:

The bug was caused by an uncaught nullpointer exception. This exception was induced because the "undesirable character filter", which is used whenever a network file is exported, sorted out apostrophes, so the graphML export function could no longer match the organization names in the statements with the organization names used in the actor attribute manager in the bottom bar -- whenever the function encountered a name with an apostrophe.

Warning: the undesirable character filter may cause some other similar bugs. Whenever statement frequencies in the nodal attributes in a graphML file report 0, this should be suspicious.
