Nemo crashes when copy/pasting text from a filename (100% reproducible)

[nick-s-b]

nemo 3.6.5
 * Is issue with desktop or windowed nemo?
windowed

 * 32 or 64 bit

Issue
Nemo crashes when I copy text out of a filename.

Steps to reproduce

1. Select List View
2. Select a file and go into edit filename mode
3. Right click and select some text from the filename
4. Click on another filename
   Nemo will now crash.

Here is the video of the crash: https://my.mixtape.moe/ghlxkr.webm

Expected behaviour
After you've clicked on another filename, Nemo should exit out of the edit filename mode. It shouldn't crash.

@leigh123linux could you please teach me how to produce a useful backtrace after a crash. Thank you!

[leigh123linux]

@nick-s-b You need to recompile, see https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces#Building_and_installing_the_package

[Zedruide]

Me too, same bug. (Arch).
