Status changed to 'Confirmed' because the bug affects multiple users.

Workarounds: gparted and mkusb manage to do what gnome-disks cannot do (I have tested in the same system).

[sudodus (nio-wiklund)]

Second workaround: gnome-disks works if wiping the whole device (in the format menu) before creating the partition and file system. But this is very slow.

It is enough to wipe the first megabyte (actually mibibyte 1024x1024 bytes) which takes less than 1 second compared to 6-16 minutes to wipe the whole device in typical 4 GB pendrives. Wiping the whole device is also causing unnecessary wear of the flash hardware.

It possible to do it stepwise. First the partition is created and in the next step the file system.

The tools are there but the internal work flow is buggy. Average users will give up long before they have explored all the alternatives.

-o-

Third workaround: It works with root privileges, but I guess this is not what you developers want ;-)

sudo -H gnome-disks

First 'Format disk' to create a new partition table, then 'Create partition in unallocated place' at the plus sign.

Some notes -- This seems to happen after creation of the partition, but before formatting it.
Easiest workaround I have is just relaunch gnome-disks and format the partition it created just before crashing.

I was creating a Ext4 filesystem on an SD card. AS far as I could tell the process had completed several seconds before the crash report came up.

[Thomas A. F. Thorne (tafthorne)]

Actually, having looked at the SD card again it seems that the old partitions were removed but the new partition was not added.

Making a second attempt after reopening the Disks application seemed to work.

Hi,

I have Linux Mint 18.3 (it's based on Ubuntu 16.04)
I am about UDisks 2.1.7 (gnome-disks)

When i try to make LUKS partition in USB flash drive (SSD Samsung 1Tb) i regulary got crash
When i run from 'root' (sudo -H gnome-disks) user i got crash again but i have core file. I got backtrace there (to see atached file)

I hope this will help to understand this bug and to patch it. It's annoying users (i am sure) :( I cannot make partition through standard utility of disks for Linux Mint.
