Issue
When in Icon view, nemo crashes when trying to rename a folder. Crash also happens when I try to create a new folder and name it immediately.
This is not a new bug and has been present in previous versions too. I do not know what causes it but I think the crash happens when nemo is still generating previews for files in the folder.

Steps to reproduce

0. Make sure you're in Icon View
1. Enter a new folder that has lots of items in it and make sure the thumbnail cache is empty
2. Quickly Create a new folder (Shift+Ctrl+n)
3. Name it something and press Enter.

nemo will crash if nemo is still generating previews when you hit the enter key.
I am unable to provide a 100% reproducible crash because it doesn't happen every time. But given the above steps, it should crash often.

I can't reproduce this (ever) - can you give me some more details - do you have any extensions enabled? Can you reproduce this with all disabled?

The only issue I know of that comes close to this is one I currently have with nemo-dropbox (but only while inside the dropbox folder tree)

Can you try to get a trace of this?

Unfortunately it would ideally require you have debugging symbols, and I see you're using Arch, which doesn't supply them even as optional packages as far as I know. I'd like to see a trace with at least nemo, gtk and glib's symbols, though just nemo's would be a decent start.

If you get that, run gdb nemo, then run, then make nemo crash. At that point do thread apply all bt and capture that output.

Thanks

I believe I have a computer where this is occurring and I'd be happy to get you a trace if I can. It's occurring on PC that is a 2 hour drive from me so this may take a bit of time.

[SparkyBluefang]

Nemo version 4.0.6
Windowed
Gentoo
NVIDIA Corporation GM107GLM [Quadro M2000M] (rev a2) 415.25

I encounter this SEGFAULT when I try to create/rename a folder when the current folder is "Loading" (progress indicator in the lower right of the window). If I wait for it to finish, I can successfully create a folder. I generally only run into this crash when I'm browsing a folder that has a large number of images or videos, and it has a lot of thumbnails to generate/render.

STR:

1. Open a folder with a large number of media files.
2. While nemo is "Loading":
   A. Create a new folder.
   B. Rename an existing a folder.

Expected results:
2A. A new folder is created with the desired name.
2B. The existing folder is renamed with the desired name.

Actual results:
2A. A new folder created with the name Untitled Folder # and nemo crashes.
2B. Nemo crashes with out changing the folder name.
