So, what would be the problem with sweeping the dust under the rug?

If the current version of the deb package for ImageMagick uses QuantumDepth=16
and does not have HDRI support enabled, then it would likely make the deb
package for Xastir work better for a while, until such time as the ImageMagick 
package maintainer decides to make that package's options consistent with the 
GraphicsMagick build.

It would probably be a reasonable temporary fix to the deb  package.

I was speaking more generally of fixing Xastir in a more comprehensive 
way for a more permanent fix for all systems (or at least a less temporary 
fix, given the instability of *Magick's API and defaults).
