Cannot generate release with piqi as a dependency

[chaos-ad]

I'm trying to generate a release for my project, which depends on piqi, but I'm getting this error:

ERROR: Unable to generate spec: read file info <...>/test/test/rel/../../test/deps/piqi/piqic-erlang/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/piqi/src/piqic.hrl failed

I'm using the latest rebar built from the basho's sources (78fa8fc), and head of piqi-erlang (7276acc).

Everything I did is I've created a dummy project (which was releasable), and added a
{piqi, "", {git, "git://github.com/alavrik/piqi-erlang.git", {branch, "master"}}}
line to my rebar.config's deps section.
