Bug 351019

Application: kdeinit5 (15.04.0)

Qt Version: 5.4.2
Operating System: Linux 4.1.3-200.fc22.i686+PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I was moving directories and files around on a drive.  Cleaning up duplicates.

Notice problem seems to be related to tab complete.  If I use tab completion, the issue seems to happen more often.

I tried to submit this information under a previous bug report but the Crash Reporting Assistant wouldn't let me select the associated bug using button with the plus sign.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
