You missed the list in your last reply. It is quoted below, and I've
attached the file you sent me as well (table.txt).

I've found that this isn't related to threading, and seems to be a bug in
TextView; my guess is embedding TextViews inside TextViews is somehow a bad
idea.
This error only effects Gtk+-2.0 (at least 2.24.13), and does not effect
Gtk+3.0 (3.6.4)
I have attached a more concise version of the program that produces the
bug. I found that if you delay the show_all on the embedded TextViews to
another g_idle_add, you don't get the error.
I believe the code is valid, so if nobody else has a comment you might want
to file a bug. I don't know if Gtk+2 gets bugfixes anymore though..
The error is:
Gtk-WARNING **: gtktextview.c:4610: somehow some text lines were modified
or scrolling occurred since the last validation of lines on the screen -
may be a text widget bug.
Gtk:ERROR:gtktextview.c:4611:gtk_text_view_paint: code should not be reached
