Description Erec 2017-06-28 12:59:45 UTC

Application: plasmashell (5.10.1)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.4-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Used the system tray icon to unmount an external drive.
The external drive was previously unmounted via the terminal.
The external drive is encrypted with luks and has a btrfs.
I wanted to label the drive, but could not figure out why the mounter (system tray icon) kept calling the drive the old name (drive == USB Key)
Btrfs told me the real name of the drive via the "sudo btrfs filesystem label /dev/dm-3"
The mounter still had the old ext4 label. I could do nothing to change what it showed up as.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
