I cannot reproduce this bug on windows. Please list the exact steps you take to create the bug. Please include which canvas you are using (Legacy, Modern Accelerated, or Modern Fallback). Does this occur with any footprint or a specific footprint? If it's a specific footprint, please include a copy of the footprint with the bug report.

Changed in kicad:
status: New → Incomplete

1) Open Pcbnew;
2) Open the footprint editor;
3) Open any footprint (here I reproduce even with the build in library);
4) Select and copy some silk;
5) Try to past, can have 2 think:
5a) Nothing, really nothing doesn't past and you try again. So really happens (5b).
5b) Crash and segment fault.

In both: Accelerated and Fallback. In legacy I wasn't able to copy anything on Footprint editor, maybe this option is not available.

It won't reproduce with edges. Has to be a module text item.

Sorry Jeff, but it is not fixed: it crashes on my install (W7/32bits).

Because you are saying:
"Has to be a module text item"
I am guessing the crash is mainly due to the fact mandatory fields are copied, which is not allowed, or not mandatory fields are copied with the same field name, which ids certainly not a good idea.

Also now in just compiled few minutes ago 201808071515+539ca5a~66~ubuntu16.04.1, this crash still.

@JP, we do appear to convert them to TEXT_DIVERS. The bug I fixed was that they didn't have a viewPrivData defined yet, and we crashed trying to see if the new item was visible (which isn't necessary in ModEdit anyway because we make everything visible).

Sounds like there might be an additional bug (or my fix wasn't sufficient).

Not present in version 20180809.
The @kicad-janitor wasn't present on Ubuntu due a compilation farm problem already fixed.
