[Insight-users] metaDataDictionaryArray in python

[Bradley Lowekamp]

Hello,

I have some ideas about your crash. I have had odd behavior with aliasing problems with some objects in WrapITK. Specifically, in my case I was calling ImageFileReader.GetLargestPossibleRegion(), and then manipulating that returned object. It took me quite a while to track down a bug, which was cause by manipulating the actual internal ImageRegion from that method, as an implicit copy was not created even though the C++ method return a const reference. I have a felling your problem, causing a segfault, is related.
