Can't run Blender scripts

[Nick Grant]

Binary package hint: blender

I have been having trouble getting blender's default scripts to run. They work fine in Windows XP but I get an error whenever I try in Ubuntu.

I get an error message saying "Pytthon script error: check console".

The console says something like:

    Traceback (most recent call last):
        File "<string>", line 110 in <module>
    ImportError: No module named BPyMessages

The line # and module name vary depending on which script I try to run, but the module name always seems to start with "BPy".

I have only been having these problems since 2.46 was released. I am running Ubuntu 8.04

I have a similar problem with some default python scripts, like Mesh -> "Solid Wireframe"

I'm using Ubuntu Jaunty 9.04 with Blender 2.48a.

I tryed the official version from the official site of the program and it works nicely, so the problem is linked to the Ubuntu package

This problem is caused by the layout of the scripts directory which prevents scripts from importing functions from any of the standard Blender scripts. I've modified one of my scripts with a workaround which I've shown as a patch below. Hopefully this will help someone fix this issue in the Blender package. The problem is that import is expecting the scripts to be in /usr/share/blender/scripts/ not /usr/share/blender/scripts/blender/ - that extra subdirectory causes the problem. Moving the scripts up a directory fixes all the standard scripts.
