Bug ID: 444373
Summary: Crash on unmounting last flash drive
Product: plasmashell
Version: 5.22.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Disks & Devices
Assignee: plasma-b...@kde.org
Reporter: thesource...@gmail.com
Target Milestone: 1.0
SUMMARY
plasmashell crashes often (not always) when I unmount last flash drive (i.e. no
more disks/partitions remain in "Disks and devices" applet). Crash does not
seem to happen if the list is not empty after unmount.
STEPS TO REPRODUCE
1. Mount and then try to unmount the flash drive via applet so the list of
disks becomes empty
2.
3.
OBSERVED RESULT
Thread 1 "plasmashell" received signal SIGSEGV, Segmentation fault.
