Dear Maintainer,

   * What led up to the situation? I was using the magic wand (or whatever it's
called
                                   in GIMP) to select some areas and make them
                                   transparent in a JPEG image that I had
opened. I
                                   tried to export it as a PNG image.
   * What exactly did you do (or not do) that was effective (or
     ineffective)? Exporting the image
   * What was the outcome of this action? It crashed, and keeps crashing
whenever I
                                          open it.
   * What outcome did you expect instead? It not to crash.

`reportbug` says that there is a newer version of GIMP available, but APT says
I'm on
  the latest version.

Attached are the GIMP crash logs and a screenshot of the GIMP terminal output
when I reopened it.

This `reportbug` program is new to me (I've never had to use it before), so I
might have some incorrect formatting, repeated attachments, etc.

Also imma plug my website for no reason whatsoever: www.silvanzwick.com
