No, we can't see what ROOTDIR is, since you read it from the config 
file.  And you don't show us the results of those prints.  You don't 
even show us the full exception, or even the line it fails on.

I doubt that the problem is in the ROODIR value, but of course nothing 
in your program bothers to check that that directory exists.  I expect 
you either have too many characters total, or the 232th character is a 
strange one.  Or perhaps title has a backslash in it (you took care of 
forward slash).

While we're at it, if you do have an OS limitation on size, your code is 
truncating at the wrong point.  You need to truncate the title based on 
the total size of src_file and dst_file, and since the code cannot know 
the size of ROOTDIR, you need to include that in your figuring.
