Summary0015215: Crash with h5parts data and histogram
DescriptionWe have found a show stopper bug that creates a crash when running h5part data into the histogram filter. This is needed for an active project. Here is how to replicate:

* Remote server, I used 8 pvservers, Linux, master. Does not fail local
server. (Note to self - redsky)

* Open DoNotRelease-particles.h5part. Xarray == x, Yarray == y, Zarray == z. All vars on, apply. Ask me for this file, I may give it to Kitware. (Note to self tomH/case2.)

>>Note - Next, we want to threshold the data such that for some time step, there is no output from the threshold filter. This will change over time.

* Threshold. Scalars id. Minimul == 1000, Maximum == 1,000,000. Apply.

>> Note - you can play time forward and backward, all is well.

* Go to last timestep. (otherwise, the histogram filter is grayed out.)
* Histogram filter. Apply.
* First timestep.


This needs to be in 4.3. Please talk to me if that isn't possible.

    BUG: If there is no data, the extents array is NULL which causes a segfault.

Dan reminded me that you need to load the h5partreader plugin.
