Extension "Text_Extract" has a misleading text in return message

Steps to reproduce:

  • open Inkscape
  • open any file which contains texts, e.g. here:
  • alternatively, create a text, e.g. "Hello World" in a new file
  • from the menu, choose "extensions" -> "text" -> "extract" Text_Extract

What happened?

  • Extension message comes back without a title, but a header stating "Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the result will not be as expected" This happens regardless whether there was an error, or a partial extraction of the text or a sucessful extraction.

What should have happened?

  • Message should have a title stating what extension it came from (especially as the script runs really for a long time)
  • Message should react differently in case of error / no error

As far as I've experienced, there are at least three cases possible:

  • Success - all texts extracted if only English characters (in older Inkscape versions <= 0.92.4)
  • partial success - all texts up to the first non-English character extracted (in older Inkscape versions <= 0.92.4)
  • failure - nothing extracted, but an error message (in Inkscape alpha 1.0, separate bug report)

Inkscape Version and Operating System:

  • Inkscape Version: all (1.0 alpha, 0.92.4, previous versions)
  • Operating System: Windows
  • Operating System version: Windows 7 German Enterprise, Windows 10 Home German
