[rdiff-backup-users] Assertion error after upgrade

[Keith Edmunds]

I've just upgraded from  0.13.4 to 1.1.5 on a number of servers. Most 
run just fine, but two of them give this assertion (below). Is this a 
known problem?

Command: rdiff-backup --print-statistics --exclude-globbing-filelist 
/home/rdiff-backup.exclude --create-full-path /home 
backup3::/backups/b_xxx/xxxxxxxx/home
