This problem I couldn't verify. The "file" was an empty folder. The 
problem occured even when I deleted and recreated the folder.

I deleted manually the last backup files but the error still occured.


The solution which solved this issue was a full backup (usually I use 
full-if-older-than 7 days). After that even a normal incrbackup went 
through without any problems.

I guess you are right when you say that there was a trashed sigfile. 
Obviously I deleted the wrong one.
