I'm new to Tk so it might be something that I might be doing wrong but I have a
crash that I can't find the cause to.
The error message I get on the crash is:
python(19468,0x7fff70f5cbe0) malloc: *** error for object 0x1002c5a10: double
free
*** set a breakpoint in malloc_error_break to debug
Abort trap
This is using the standard 2.6.1 version on OS X 10.6.3, but version 2.5 give
the same result.
When I try this using a linux box (v2.5.2) the program runs as it should.
I tried to using the debugger to single step through the critical lines and it
seem to crash when it should return from a menu item handler.
The code for that handler looks like this
def saveToFile(self):
filename = dlg.asksaveasfilename()
self._storage.store(filename,self._win.getText())
Single stepping seem to indicate that the call to self._win.getText() works
just fine, the store command saves some text to a file and the file is created
with the correct text, but then something seem to happen:
(Pdb) s
--Return--
> /Users/jem/Desktop/testing.py(96)saveToFile()->None
-> self._storage.store(filename,self._win.getText())
(Pdb) s

release of previously deallocated object (0x1011466f0) ignored
Does anyone have an idea what could be causing this?
The complete code is available at <http://tmp.myownsnapshots.com/pyproblem>
(and yes, I know that the code looks a bit strange but I have my reasons :)
