Bug 391055

Application: baloo_file (5.32.0)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.114-42-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
I had opened a folder in Dolphin that was provided over KDE Connect by my phone. I right-clicked in empty space (in the file pane) and went with my mouse cursor over the right-click menu, probably causing submenus to load. Eventually the crash happened without me having clicked an option.
- Unusual behavior I noticed:
My entire operating system (or probably just the X server) froze for around three seconds.
After the crash had occurred, when opening the right-click menu, it took a long time (around six seconds) to show the "Create New"-submenu and it fails completely to show the "Link to Device"-submenu of the "Create New"-submenu.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
