Unhandled exception in Collect tab when changing slice viewed

[raimund-schluessler]

Opening this file (exported by BrillouinEvaluation, same happens when coming from bmlab)
Brillouin_rep1.zip
by Add Image Data in the Collect tab and then changing the slice viewed with the View slice slider leads to this error:

Unhandled exception in Impose version 0.3.1:

Weird enough it only happens when dragging the slider with the mouse, but not when clicking onto it or using the keyboard.

Thanks! This was due to a confusion with QWidget vs QTableWidgetItem.
