Comment 6 for bug 399938

An identical error is breaking Launchpad tests (specifically gina.txt) on Karmic. The "dpkg-source -sn -x" failures are not always reproducible, and I haven't ever been able to reproduce with an identical command called from a shell rather than Python. Only some packages (ubuntu-meta 0.80 in the gina test archive is the one that fails most of the time) are affected.

This is all in a karmic i386 chroot, but with an amd64 kernel. Debian bug #523329 looks very relevant, but that's meant to be fixed.
