Error using GTK

Question

When trying to use this gtk code:

import gtk
tv = gtk.TextView()
b = tv.get_buffer()
t = "Let check this out.\x00"
b.set_text(t)

I get this error:

GtkWarning: gtk_text_buffer_emit_insert: assertion `g_utf8_validate (text, len, NULL)' failed

The text is generated automatically here, which I showed, for example. I wanted to put this line in a text buffer, but I cannot. Help me out with this.

Answer 1

I believe this is due to the weird built-in 0-byte at the end of the line t(part \x00).

I don't think you can expect / require GTK + to support binary data in GtkTextBuffer, it just requires the text to be in UTF-8. Remove the false 0-byte.
