Changes (by simonpj):

  * status:  new => infoneeded


Comment:

 There's definitely something wrong, although it's harmless I think.
 However
  * It's hard for me to reproduce because I don't much want to go through
 the process of building all of Hets
  * It's to do with default methods, which is being up-heaved by Pedro
 anyway

 I think the best thing to do is to wait for 7.2, and try again then.

 Meanwhile if you felt able to cut it down to a test case that'd be even
 better, but you may not want to bother since it's doing no harm meanwhile.

 Simon
