bzr git-import complains about "invalid object name"

Hi,

I am not able to import the Verilator GIT repo in Launchpad (for a daily receipt). This is what I get if I try to import it on my machine. Another question is, if a fixed release would be created, when would it reach the PPA build servers for Precise?

Git version used to pack the files is 1.7.0.4 and the Apache HTTP server is version 2.2.14, there seems to be nothing wrong with the GIT/HTTP server, so I assume the issue is in bzr-git.

Regards,
Iztok Jeras
