Bug 376203

Application: dolphin (16.08.2)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to open a terminal, using [F4]

- Unusual behavior I noticed:
The terminal opened (very) shortly and then closed again. (Just a sort of flicker)
I tried this several times, after some tries dolphoin crashed with this info.
I have already seen this behaviour (terminal closes immediately) before, but no crash.

When I retried another time, it didn't hapen; "even" not when going to the same directory I had been in.

BUT: Suddenly the terminal now stays open (as expected)
This now also works again for the next dolphin I started.

(Don't know if thsi is helpful, given the fact, that the crash occured just once)

The crash does not seem to be reproducible.

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