Bug#813426: [Pkg-gmagick-im-team] Bug#813426: warning: /etc/alternatives/compare is dangling; it will be updated with best choice

[Vincent Fourmond]

control: unmerge -1
control: reassign -1 src:imagemagick

  Reassigning this bug to imagemagick. There are two problems:

  * the problem with the alternatives
  * the problem with dir to symlink

  The latter is clearly a dpkg bug (already reported), but the former
is an imagemagick bug, and should be tracked separately.

  Bastien, I'm handling the alternatives problem right now. Shall we
revert the dir-to-symlink change as of now ?

  Regards,

  Vincent

Oops I'm sorry I neglected to truncate them for my bug post.

No I had to use ^C to stop them.

Dear ow...@bugs.debian.org, can you please truncate some of the repeated
messages I accidentally forgot to truncate.

  This looks like a dpkg bug -- dpkg doesn't like so much switching
from arch:any to arch:all, as far as I can tell.

  BTW, you show a very long list of warning messages, did they stop by
themselves ? If yes, I'm very curious why.
