[rdiff-backup-users] Possible python 2.3 dependency?

[Chris Wilson]

Hi all,

I've been using rdiff-backup 0.12.8 for several months and am very heppy with 
it. Thank you all for your hard work!

Now I find that 1.0.0 has been released, and added to the freshrpms repository, 
so all my FC2 boxes have upgraded themselves automatically :-|
(this is not your fault, of course, but freshrpms).

It seems that 0.12.8 is not compatible with 1.0.0, I get warnings about 
mismatched versions and rdiff-backup crashes with a stack trace (I can provide 
details if required).

So now I have to upgrade all my boxes to 1.0.0, including Gentoo ones which 
don't know about 1.0.0 yet (wasn't Gentoo supposed to be "cutting edge"? ;-) 
Either that, or downgrade all my FC2 boxes to 0.12.8.

It seems that 1.0.0 has some nice features like filesystem feature 
determination, that I would like to use. I hope that I can upgrade them all. 
And I'm almost there.

The last box to upgrade runs FC1. It's old and delicate. I built an RPM from 
source, it runs, but crashes when trying to back up:

<stack trace>

</stack-trace>

So it seems that rdiff-backup 1.0.0 doesn't like python 2.2? I really don't 
want to upgrade python on this box (it would be easier to upgrade the whole OS, 
or to extract teeth from an angry camel).

The front page of the website says that only Python 2.2 is required, and the 
change log says only this:

>  rdiff-backup should now work and build with python 2.3.  Thanks to
>  Arkadiusz Miskiewicz and Arkadiusz Patyk for bug reports and a patch.

Could it be that this change has broken something?

Cheers, Chris.
