Issue
Using silx.gui.dialog.ImageFileDialog leads to unpredictable crashes, when interacting with hdftreeview (i.e. the NEXUS explorer or database).
These crashes are not caused by python exceptions and there are no error messages.
Looks like segmentation fault or similar. This problem is probably hard to debug and caused by the external silx library.
Workaround:
Using a file explorer to select images and fabio to read images is working.
