read_paf 'Error in if (nrow(tag_mx_nr) == 0) { : argument is of length zero'

Hello and thanks for a beautiful package!

I'm having some trouble with the read_paf function. When my paf file only contains one line I receive the error message 'Error in if (nrow(tag_mx_nr) == 0) { : argument is of length zero'. Adding an arbitrary line to the file seems to solve it.
Have you encountered this or know what might be causing it?

Any help or suggestions appreciated!
Thanks!
