Description Björn Lindqvist 2007-02-10 19:41:41 UTC 
Minimal snippet that demonstrates the bug:

import gtk

class WeirdEntry(gtk.Entry):
    def __init__(self):
        self.hadj = gtk.Adjustment()
        self.hadj.connect("value_changed", self.hadj_cb)
        super(WeirdEntry, self).__init__()

    def hadj_cb(self, adjustment):
        pass
    
if __name__ == "__main__":
    widget = WeirdEntry()
    widget.hadj.handler_block_by_func(widget.hadj_cb)

Version:

Python 2.4.4c1 (#2, Oct 11 2006, 21:51:02) 
[GCC 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)] on linux2

the above crashes the interpreter with the following error:

Exception exceptions.SystemError: '../Objects/funcobject.c:128: bad argument to internal function' in 'garbage collection' ignored
Fatal Python error: unexpected exception during garbage collection
Avbruten (SIGABRT) (core dumped)

On Windows XP with Python 2.5, the above code runs without a problem. So maybe this bug is not PyGTK-related. On the other hand, it could be that a fix in Python has exposed a big bug in PyGTK.

Works for me with python 2.4 on Kubuntu:
Python 2.4.4 (#2, Feb 16 2007, 16:57:19)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu1)] on linux2
PyGTK versions is 2.10.4-0ubuntu2
