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

Added a number of pyweather applets (5+ ?) as well as several analog clocks (there are no other applet on this desktop, apart from the Desktop folder and panels).
While configuring them all, yet plasma stopped to react normally : slow downs, no longer repositioning applets if dropped a little too close from desktop border, etc.
Then, some clocks started to "disappear" while moving them around (later, found 2 of them - not all - at the desktop top left, somehow hiden behind panels).
This was rather obscur, since at the same time, I could not *read* (system monitors, top) that hardware resources were being overcharged.

Locked widgets and restarted "to see where we were". Applets were loaded before network was established (wifi/nm requires unlocking kwallet). Pyweather applets all displayed "connection error", which is normal too.
However, even after network access had been restored, their refresh buttons had no effects.
That's when the crash first occurred, if I remember it all correctly (was a few hours ago).
After the crash, applets were appearing to function normally. Clocks appeared each with a different vertical position, "stairs effect".

DrKonqui picked it up and I started downloading debuginfo packages.
Overall plasma remained hardly responsive, until I removed multiple pyweather occurences, apparently.
Crash occured again while doing this (DrKonqui kept running thou).

- Custom settings of the application:

A few different timezones and calendars for each clock, as shown in the backtrace - same for pyweather applets.
I assume such setup should be expected.

I may provide additional information if it helps.
Thanks,
Xavier
