integer out of range for 'L' format code

[plaa]

I'm trying to convert the wiki at http://sourceforge.net/apps/mediawiki/openrocket/index.php?title=Main_Page

After dumping all the pages and trying to convert, I get the following error:

$ ./import.py < openrocket-20121012122604.xml  > dump
Traceback (most recent call last):

struct.error: integer out of range for 'L' format code

I tried checking the code, but not being familiar with Python I can't make out what's going wrong. Any help is appreciated. The data dump is at http://sampo.kapsi.fi/tmp/openrocket-20121012122604.xml.bz2

I was also unable to run the script without creating an empty "config.py" file in the directory, the "import config" was failing otherwise. Don't know if that's got something to do with it.

On a side note, how could attachments be migrated? I was surprised there was no mention in the README.

Adding debugging before 'pack' reveals that author.id is -1, which cannot be placed into an unsigned long:

rev:1 time:1219080644 page:1 authorid:-1 flags:2

When I changed 'L' to 'l' it just broke later on in a more mysterious place. What should author.id=-1 mean and how should it be handled? It seems from the code that if the script can't parse the user the id is set to -1.
