That's a rather far-reaching config line; it will mean any and all 
(deleted) files will be ignored by the libs test, if you've put it under 
'*' !

The crucial line in the libs script is

return 1 if $path =~ $regexp;

i.e. you want a perl regular expression for the entries in 
libs.local.yml. Given you mentioned

/nfs/home/jwinius/.xsession-errors (deleted) nfs.umrk.nl:/nfs/home)

you could thus try, perhaps,

- '^/nfs/home/.*/\.xsession-errors '

(NB the trailing space is deliberate, given the example string you'd 
like to match).

Look for online tutorials about perl regular expressions if it's not 
clear what's going on there.
