Description Tony 2017-02-11 14:36:44 UTC 
Application: kwin_x11 (5.9.90)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.9.9-040909-lowlatency x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:
I was opening a crazy amount and really fast of "Dolphin" instances trying to reproduce a bug, end up finding this one.

- Custom settings of the application:
I have set a shortcut to open Dolphin to "WIN+E"

I encountered it first using "nouveau", but my screen goes black or hangs, can't swicth to another VT on top f it. 

Got this from dmesg:

[ 1713.353357] nouveau 0000:01:00.0: fifo: read fault at 0000011000 engine 07 [HOST0] client 06 [HOST] reason 0c [UNSUPPORTED_KIND] on channel 29 [007ddf8000 dolphin[4670]]

and from journalctl | tail a lot of:

feb 11 00:45:30 joder-GA-78LMT-USB3-6-0 kernel: nouveau 0000:01:00.0: fifo: SCHED_ERROR 0c []

I installed nvidia's driver 378.09 tried again. This time the desktop goes slow at first until it got unresponsive, after a while the desktop got slowly back to normal and drkonqi pop with this crash.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

Unfortunately the backtrace is lacking debug symbols. If you are able to 
reproduce please install the debug packages provided by your 
distribution (please ask the distribution support channel on how to 
install them) and attach a new backtrace.

Ummm weird i swear i have kwin-dbg or kwin-dgbsym installed. Most of the "libqt5*"
do not have debug packages on neon.

I don't have this system anymore, i did try to trigger it on my present one, with nouveau and property drivers,no crash just a slow down as the dolphin instances loaded up.
