Error on vb.net file

Hi,

I try to generate Gtags on vb.net files and I have these errors :
$ gtags --explain

• File 'GrblErrorsSingleton.vb' is handled as follows:
  suffix: |.vb|
  language: |VB.net|
  parser: |parser|
  library: |/usr/lib/gtags/pygments-parser.so|
  ctags: Unknown option: --gmap-vb

  File "/usr/share/gtags/script/pygments_parser.py", line 155, in parse
  self.child_stdin.flush()
  BrokenPipeError: [Errno 32] Broken pipe
  gtags: unexpected EOF.

Do I make something wrong ?

Thanks

I found the solution to my problem.
There was a wrong vb.ctags in my ctags config directory.
I deleted this config file and every thing is correct.
