Hi,
I have a cell renderer written in python which derives from
gtk.GenericCellRenderer. When I run my program with gtk.threads_init(),
python crashes when I try to set a property on the cell renderer. It
dies in a call to PyObject_CallMethod(). For other crashes I've seen
like this, wrapping the calls in
pyg_block_threads()/pyg_unblock_threads() fixes the problem, but when I
try it this time, I get:
Fatal Python error: PyThreadState_Get: no current thread
The program crashes in gobjectmodule.c:pyg_object_set_property(), trying
to call my object's do_set_property() method. I noticed that
pygtkcellrenderer.c doesn't overload the set_property() and
get_property() methods on GObjectClass. Maybe it should call
pyg_block_threads() and chain up to its parent? I'll try it and send a
patch if it works.
Here's are a few frames from the stack trace:
