cinnamon/nemo crash after samba umount

[bruno]

I have found a bug affecting (at least) mint 17.2 cinnamon 64 bit.

Steps to reproduce:

0) Make sure you have at least one icon on your desktop
1) Share one of your folder with Nemo (right click...) and check the box for guest access
2) with Nemo, browse the network and mount this shared network (on the same computer or not)
3) The folder will appear in the network mounts (Nemo side pane). Right click on it to make a shortcut and then unmount it.
4) Click on the shortcut to remount it.
5) Unmount it ===> Crash: no desktop icons, broken right-click on the desktop, broken Super key, hidden panel...

The workaround then is to restart cinnamon.

I hope this is clear.

It seems that the samba umount makes nemo crash (in the same way as entering nemo -q in a terminal). So another workaround (after the crash) is to force nemo to reload by toggling the switch the top of the desktop settings to "off" and immediately back to "on".

This bug first appeared with Linux Mint 17.0 and is much more severe than what is mentioned in the bug description. If you have a local file/directory copy/move operation going on when ejecting (unmounting) a samba share then the operation is abnormally terminated, and data corruption occurs! Extremely nasty to have data corruption occurring with a bug like this.

Bug is not critical in nature since there is a workaround. When Cinnamon crashes the desktop can be restored simply by going to a local place (eg "Documents") via "Menu" -> "Places". If Clem is reading this then he urgently needs to get this issue fixed before the Linux Mint 17.3 release arrives. This issue is very severe and could easily become critical if it isn't resolved quickly. Accessing a samba share via Nemo is a very common use case in Cinnamon.
