Bug Description

I've had problems for a long time with eeschema spontaneously crashing, whereupon both the eeschema and kicad windows disappear and I have to restart them, having lost all my changes. I've never reported it before because I didn't have a way to reproduce the problem.

I now have a 100% reproducible case with the current nightly build. Here's a link to a movie of it: https://drive.google.com/open?id=1al-GuxCqZZbYQDO_FmxCu1193ANsV-qj, and here is a link to the archived project I'm using in the movie: https://drive.google.com/open?id=1tfvt2-EHsk-SQxJ191TeVUfBvEJajKzY

Here's what's in the movie:

1. I place a text string ("2004004-004", size 130 mils, bold).
2. I hit ctrl-C to copy it.
3. I move the cursor to where I want to put the copy.
4. I hit ctrl-V to paste it.
5. Blooey!

Here's an alternate sequence that also crashes every time, I think, though I didn't put it in the movie:

1. I place the text string, same as above.
2. I hit ctrl-D to duplicate the string.
3. Blooey!

As a fun(?) experiment, I have retried this experiment with an earlier nightly build from a few weeks ago as well.

The results are roughly the same, except that sometimes when I do the ctrl-V to paste the text eeschema may just freeze and need to be explicitly sent a KILL signal rather than just abruptly exiting.

It appears to be a corrupt D_LIST. It crashes when it finds a SCH_FIELD whose m_viewPrivData has been freed (or perhaps the upper bytes walked on?). In any case, the pointer doesn't look right (0x900007ff1f82bdc3 -- what's with the '9' at the top?) and produces a segfault.

Note: This crash happens anytime a non-select tool is active when doing to copy/paste or duplicate.
