SubversionException: 160043 - Expected FS format between '1' and '7'; found format '8'

When we try to connect to our subversion repository we see the following python stacktrace:

"Old" libsvn version?

[cmanley]

Perhaps it's an old libsvn version or a bug in viewvc. If it's the latter then it's probably better to create a new issue in the viewvc project along with the file system type you mounted.
You can search for the error message and find other projects with similar error messages dating from 2012 even.
