Crash on image decoding: pointer being freed was not allocated

[ddska]

Adium with telegram-purple plugin crashed after I received a photo and tried to view it.
Here is the detailed report:

The crash doesn't seem to be directly related to the incoming image:

This is likely to be the same issue as this. Please try this patch out (minimal version) and report back whether this works or not.

I can't reproduce this, it happened just once.
Any idea how I can check it if it's fixed or not?

[BenWiederhake]

I already know how to check whether the "message double free" patch works, that's why I'm sure it fixes that issue.
However, I have no idea how to trigger any weird behavior with images.

So, I'll just this of this as "fixed", and please do complain/reopen if there's any further issue.
