[Visualpython-users] last, desperate call for help

[Fionn B. <fi...@sp...>]

Hi all,


I have asked earlier, I do it again. We have a project here that needs 3d
output. the UI itself ist done in python-gtk.
We fail to manage starting vpython out of our gtk application. First the
two mainloops collided, so people told us to use python-gtk2 and threads.

So we switched the Ui to python-gtk2 and use threads. Similar to the
tk-demo thats coming with python-visual, we start python-visual in its own
thread.
The good news: no more mainloop clashing. The bad news: It segfaults
immediately, leaving loads of messages on the screen that look like this:

(<unknown>:13237): GLib-CRITICAL **: file ghash.c: line 225 (g_hash_table_lookup): assertion `hash_table != NULL' failed
(<unknown>:13237): Gtk-WARNING **: gtk_type_create(): unknown parent type `21'.

...

Please, please, if anyone EVER managed to start vpython from a gtk gui or
has any tip on what might have gone wrong, send it!

Desperate,
