[Bug 829552] Re: Pulling large branches with bzr fails in grand fashion (sefgaults, tracebacks, oh my!)

[Jelmer Vernooij]

The subject mentions "branches" - can you reproduce this with more than
just lp:checkbox?

This might be a dupe of bug 598572.

Title:
  Pulling large branches with bzr fails in grand fashion (sefgaults,
  tracebacks, oh my!)

Status in “bzr” package in Ubuntu:
  New

Bug description:
  While looking into something, I tried pulling  a branch of checkbox
  using bzr.  This started creating a local branch of the current
  checkbox trunk, however, after a certain point, bzr crashed with a
  traceback and a partially filled directory.

  bladernr at klaatu:~/development$ bzr branch lp:checkbox
