Is the source code of the referenced software online? Is it free  
software? If yes, there is a chance we can look at changes in that  
software.

Also, does the software dynamically link in shared libraries? Or has  
it been built statically?

I guess that there is a flaw in nx-libs that gets triggered by your  
application. If we could generate diffs of the different EMAN2 2.0  
versions, we might be able to track down the cause for the mirroring  
effect.
