SIGSEGV in nemo_file_can_set_permissions (file=file@entry=0x0) at nemo-file.c:5084

[ghost]

I encountered this crash on Debian Stretch AMD64:

Package: nemo
Version: 3.2.2-3
Severity: normal

nemo crashes when double clicking on a desktop icon which is a link to a website.

The desktop file is named "Treasures of ancient Rome | kijk online | canvas.be.desktop" and contains this:
[Desktop Entry]
Encoding=UTF-8
Name=Koppeling naar Treasures of ancient Rome | kijk online | canvas.be
Type=Link
URL=https://www.canvas.be/video/treasures-of-ancient-rome
Icon=text-html

This is the backtrace of the crash when double clicking this icon on the desktop:

Program terminated with signal SIGSEGV, Segmentation fault.

I created the same file on Linux Mint 18.3 Cinnamon with Nemo 3.6.5, and double-clicking it works as expected (opens the link in web browser). If this issue still affects you please test against the latest Nemo version (3.6.5 currently), go through troubleshooting (see our guide) and create a new issue if the responsible component proves to be Nemo.
