Yes, you're right.  When I went looking I didn't find the other issue.  Thanks, and sorry for the noise.

Created attachment 335174 [details]
patch from Debian to fully correct the issue

Actually, it just came to my attention that this is more than just an absolute path traversal issue, and that using "../" works as well, which the patch noted in bug #487132 fails to address.

I'm going to attach the patch that Debian is planning to use, although updating to 3.0 will also correct the issue.

Ok, I'm updating to 3.0.0
