Title:
  dpkg -i crashes when .deb contains utf8 filenames

Status in “dpkg” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: dpkg

  While creating some .deb packages, I noticed that dpkg -i crashes when the deb file contains some utf8 filename combinations.
  It doesn't crash for all utf8 filenames, but only for some of them. I suspect a buffer overflow somewhere...

  I attach a minimal .deb package which reproduces the problem; it only
  contains two directories and one empty file.

  Ubuntu 9.04, dpkg version 1.14.24ubuntu1.
