Description Walking Turtle 2019-09-09 23:19:12 UTC
Application: plasma-desktop (4.11.13)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 4.9.0-0.bpo.9-amd64 x86_64
Distribution: MX-16.1 Metamorphosis

-- Information about the crash:
- What I was doing when the application crashed:
I was setting-up YAWP as follows:  
1) Invoked Debian Weather Service. 
2) Fed it my ZIP code (wrong move).  
3) On closing the "No Such Location" panel, the entire Desktop crashed to blackscreen.  Then regenerated itself (minus some recent desktop mods done following the most recent reboot) due to having set that feature up prior.

- Custom settings of the application:  None in particular.  Telling the AccuWeather Service the ZIP worked fine.  (I still /will/ go back and try telling the Debian Service some different Plausible Things.)  But the point is the crashing of the desktop on failure (on the part of the currently-chosen service)to accept the syntax and/or ZIP code as location data.

Note:  This key data requirement varies from service to service.  But Yours truly has observed it across numerous platforms at setup-time over many years.   And no matter what:  Do it wrong for /any/ service (variable requirements;  do not know them all yet) and down goes Plasma!  And that is all. 0{:-\o[

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
