[K3d-development] K-3D Issue: Crash on python node inspection (0.8.0.2)

From: fink <djsnickles@ya...> - 2010-10-14 20:28

Software:
version: 0.8.0.2
compiler: gcc 4.3.5
build time: Oct 12 2010 13:57:56 local
platform: Darwin-10.4.0;i386
OS: OS X 10.6.4


Description:
Inspecting a node with python, or accessing its properties via Python will crash K-3D. Perhaps these errors are because of my specific build? Has anyone else built the latest hg trunk on OS X?


How to reproduce:
1) Open K-3D 0.8.0.2
2) Open K-3D's Python Shell
3) Create a node, then try to access a property of the node, or just use the shell's autocompletion; e.g.:

>>> node = k3d.plugin.create("Test", context.document)
>>> node
<k3d.iunknown object at 0x11df00ec0>
>>> node.
[press the Tab key for autocompletion, and K-3D will crash]

Sorry, I retyped this from a frozen window, and for some reason replaced the plugin name with "Test". The specific code was from here:
http://www.k-3d.org/wiki/Scripting#.22Action.22_Scripts


I just tried again in K-3D's python shell, and pressing "Tab" at the end of this code will crash my K-3D build:

>>> cone = k3d.plugin.create("QuadricCone", context.document)
>>> cone
<k3d.iunknown object at 0x11d312ec0>
>>> cone.

Works fine here.  I suggest you look at whether there are issues with
your Python libraries - it is easy on OSX to build against one version
of Python, while loading another at runtime.

Cheers,
Tim

Again, works fine here.  Clearly, something is going wrong every time
Python code is executed, so these are all manifestations of the same
problem.  Use gdb and otool to compare the Python libraries loaded at
runtime with the libraries that were linked against.

Cheers,
Tim
