Your experience is very strange, and nothing I have observed (or heard
of) before. I would associate an experience with this like a simple
human error such as working with multiple hosts at the same time, and
accidentally typing commands on a different host.

Are you dealing with just one system? Is it possible that some commands were executed on a different system?

I only had one putty terminal open

But it works now :)

/usr/local/bin/gm convert: No decode delegate for this image format (/var/vector_01.png.png)

The above is strange due to the use of ".png.png" as a file extension.
This could be forced to work (if it does not already work) by specifying
"png:/var/vector_01.png.png". But this assumes that the GraphicsMagick
used does include support for the PNG format. :-)

I do that because I optimize the image in steps. I just add the new extension so it's easy to get a grasp of the whole "chain" when debugging

The file could also be something like:

file.pdf.png.tif

in the .png.png file I think I run it through opencv and do some optimization before OCR

  This is a test to see if email makes it into the issue tracker.

I expect that what happened is that GraphicsMagick configure/build was done first, then used to discover that there was an issue, the development packages were installed, and then the configure/build was done again. Regardless, there is no bug here.
