Apport does not ensure tags are valid

Bug Description

Apport allows hooks to add arbitrary tags, and passes them through to the launchpad crashdb implementation lowercased but otherwise unmolested. However, launchpad restricts the form of tags and will raise an error both in the api and the web interface otherwise.

    "Tags must start with a letter or number and be lowercase. The characters "+", "-" and "." are also allowed after the first character."

This allows a package to incautiously create an invalid tag, then renders the bug unreportable. See bug 1029471 in the unity packaging for an example of this, which is exacerbated by bug 1024836 in apport masking the real error.

Thanks Martin! Now, if only I could get the unity packaging change landed so they treat tags more reasonably as well.

This bug was fixed in the package apport - 2.5.2-0ubuntu2

apport (2.5.2-0ubuntu2) quantal; urgency=low

  * data/general-hooks/ Add "package-from-proposed" tag if the
    installed package version is available from -proposed, but not from
    -security and -updates. (LP: #1050853)
  * Merge fixes from trunk:
    - data/apportcheckresume: Open report file in binary mode. (LP: #1040353)
    - When throwing ValueErrors, show the non-existing
      package name. This makes it easier to debug such crashes.
    - Replace characters from tags which are not allowed by
      Launchpad with '.' (LP: #1029479)
