The title of this thread should read, "Coma Caused by Bacterial Contamination" if the Norwegian news article is to be believed.
 
I've been researching this from the original news source (Norwegian) via the Google English translation. I guess bacteria is "Sørlandet"?  
 
In the WARNINGS / FAQ Section / New Peptide Users Read! thread this is spelled out in this section about sourcing a peptide:

The "contaminated" part of the warning would include bacterial contamination. This warning is very serious and highlights the need for people to start having their peptide supplies tested.
 
If the news story is accurate about there being bacterial contamination (I'm learning to be skeptical of news sources lately with their reporting of errors and falsehoods) then there's a number of possibilities for how the bacteria got there number one being that the peptides weren't stored properly somewhere along the line (most likely while in the possession of the woman).  
 
As to the cancer question, this was very much in the minds of the original researchers and they conducted a number of preclinical tests of melanotan-1 and concluded that melanotan-1 had a, "lack of carcinogenic potential" (meaning it lacked the ability to cause cancer). One obviously has to weigh their conclusion relative to what they cite in their studies. I'm researching a bit now to see what cancer research was done with respect to melanotan II.

You've got no argument from me about the gravity of what occurred but your title is sooner implicating a melanotan peptide as opposed to some other factor, meaning the casual reader says, "Oh! A melanotan peptide [itself] caused a person to go into coma!" when that is not the case. A title like, "Coma from Melanotan bacterial contamination" would be much more to the point and not easily confused.

Why would they instantly blame the Melanotan and not the bac water, or whatever else she may have used?  They wouldn't want to complicate the cautionary tale against the evil barbie drug, which is the story they wanted to write.  I once had some injections that made my skin itch, and I realize now it was almost certainly the old bac water I was using.  She could have used pond water for all we know.
 
But I am glad to see this story here.  It's good to get the info out and let people read and make their own judgments.

Can there be a bacterial contamination in something that is freeze dried? Or is it more likely that a bacterial contamination happens after it has been reconstituted?

IMHO
The most critical aspect of a melanotan-1 trial is cleanliness of the injected substance, the injection site and syringe. Always use a new syringe and clean the injection area with alchohol swab. Also clean the vials of both the melanotan-1 and bact water with alchohol all aroung the rubber lid area where you are inserting the syringe. Never insert a syringe back into a vial after touching anything but the seal on the vials. Just one bacteria in old bact water could create havoc.
Bact water is dated so you should throw out any that is close to it's expiration date. melanotan-1 does not have dates, so you should write dates on your melanotan-1 supply when you receive it so you know when it has aged. It will also let you know what order to use your supply.
Keep melanotan-1 in the freezer and Bact water in the fridge for longest life.
It is very likely that on of the big holdups for melanotan-1 getting any kind of FDA approval is due to the fact that is has to be injected vs. taken by pill.
