Seems that in trunk, the experimental LPEs are currently enabled by default for Windows builds (unlike on linux/osx):

yes, on Windows, these appear to be enabled by default, backtrace attached

I've just now disabled experimental LPEs in trunk because we are in frost now.

jabiertxof on irc noted that the crash occurs if no perspective object is defined in the current document (created by the 3dbox tool) - confirmed with 0.48+devel r12670 (with experimental LPE enabled).

I attach a diff who make some improvements to the LPE:
1. Alert if no perspective element in defs
2. Add a button to refresh the perspective if changed by editing his 3dBOX
3. Add a text box to input the ID of the perspective to use, default first perspective

The patch mitigates the problem by A) not crashing and B) getting the user's attention as to why it won't work yet.

Here the patch ready to apply to current trunk.
Changed gtkmm sub-headers to main and also improve the perspective id widget.

I need better "Grammar" for this strings:
You need a BOX 3D object
First perspective selected
First perspective
Set the perspective ID to apply
Refresh perspective
