Crash when editing name of folder and alt-tabbing

[0x7969]

 * Nemo 3.6.5-1
 * Windowed
 * DE: Cinnamon
 * Distribution: Arch
 * Intel HD Graphics 3000 (SandyBridge)
 * Mesa 17.3.3-2
 * 64 bit

Issue
Nemo crashes (Segfault) when creating a new folder (hence editing it's name) or editing an existing ones and alt+tabbing out of the window, back into it and then confirming the name.

Steps to reproduce
Create new folder or edit name of existing one, alt+tab out of window while still editing text, tab back into nemo, hit enter.

Expected behaviour
Should not crash.

Other information

does not crash in xubuntu 16.04, nemo 3.6.5, virtualbox

[d-packs]

I confirm the bug in Antergos (i.e. also Arch).

Nemo 3.6.4

OS: Arch Linux
Kernel: x86_64 Linux 4.15.5-1-ARCH
Resolution: 3520x1080
DE: Budgie
WM: BudgieWM
WM Theme: Numix-Frost-Light
GTK Theme: Adapta-Nokto-Eta [GTK2/3]
Icon Theme: breeze-dark
Font: Segoe UI 10

GPU: Mesa DRI Intel(R) Ivybridge Mobile

Confirming as well on Manjaro (again Arch):

• Nemo 3.6.5-1
• Windowed
• DE: Cinnamon
• Distribution: Manjaro
• Kernel: 4.15.5-1-MANJARO
• AMD Radeon R9 390
• Mesa 17.3.5-1
• 64 bit

I'm reproducing by

1. Editing a file name
2. Switching window focus by clicking into a different window
3. Clicking back into the nemo window

[d-packs]

Actually alt tabbing is not necessary. The program crashes if the filename loses focus while being in edit mode.
Steps to reproduce:
Start renaming a file, don't validate (i.e. don't press Enter), instead click on anything else outside of the current pane in Nemo (can be a file in another pane, menu items etc) or outside of the main Window.

All of you having the problem are using Arch. Have any of you tried getting a useful backtrace?

[LingMan]

Not entirely sure if this one is useful because I just used gdb for the first time:

[JosephMcc]

Wondering if this might be a case of Arch having newer gtk I just tested under gtk3.22 and couldn't reproduce the issue in Ubuntu18.04

[LingMan]

My gtk3 package is 3.22.28-1.

[JosephMcc]

This issue has actually been fixed in git master. See #1689 and f2eecb2

[LingMan]

Ah, great. Then we just need to wait for a release. Thanks for the quick followup.
