How to work around a suse-filelist-forbidden-backup-file condition?


I was building a package and run into the following error message (after build)

trytond_nereid_project.noarch: E: suse-filelist-forbidden-backup-file (Badness: 10000) /usr/lib/python2.7/site-packages/trytond/modules/nereid_project/templates/!project/project/emails/.project_text_content.jinja.swp is not allowed in SUSE

Contentwise it may be a VIM-leftover of the programmer.
Is there any way to work around this error, except deleting the file from the source tarball?
