Here you can see that the original version 20090123 got truncated to 36107 == 20090123 & 65535. This in itself might be a bug, I'm not sure.

I can't see this. But I do see how this assertion would be tripped.

in the backtrace, the value of the file_version argument is 36107, whereas in the XML archive, the version is 20090123. So it looks to me that something truncates the value to 16 bits.

If you comment out this assertion does this make it work?

Will do tomorrow, and report back. Thanks. David.
