Bug 391338

Application: dolphin (17.12.1)

Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
Dolphin was (probably) open on a filesystem tree that I was updating by script, changing the ownership, permissions and SELinux attributes. While a whole lot of permissions geot updated, Dolphin crashed (this happened twice). Is it overwhelmed by too many messages?

The crash can be reproduced sometimes.

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