I found a no sense result and crash when trying to obtain a catalogue of objects using a combination of Noisechisel, Segment and MakeCatalog. Step by step:
It fails with an error:

I will try to describe the context and the work around.
I have the same data image but with two different kind of distortion coefficients (SIP and PV). The goal is to estimate the sky background of the image with PV coefficients and correct for it. To do that, I need to mask all objects in the image. I do that by generating a mock image with ellipse shape like objects obtained from the catalogue.
The problem is that I am not able to obtain a catalog from the image with PV coefficients, which is the one I need.
The solution was to create the catalogue using the image with SIP coefficients and then apply the mock image to the image with PV coefficients. Of course, this is only possible because I have the image with SIP distortion coefficients.
I hope the explanation will help to other people with the same kind of problem.
