Trying to import a file that has an attached OTRS permission triggers c:MediaWiki:Abusefilter-warning-otrs. There is no way to continue the import or follow the advice given by the warning: "You may press 'Save page' again if you like to save this edit." Of course, the importer is not trying to add a new OTRS tag to a file, just import a file that already has one. The file I encountered this problem with is: en:File:Minister prostrates at the start of United Methodist Good Friday liturgy.jpg
Import fails when file contains an OTRS permission
@Finnusertop: I imported c:File:Minister prostrates at the start of United Methodist Good Friday liturgy.jpg for you. Sorry, only Global OTRS members are allowed to do that.
