Description Bertoche 2017-08-24 17:02:16 UTC 
Application: plasmashell (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.7.4-2.g6a5bbb1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I had just gone offline and then logged in again trying to update the contact list.
I logged in clicking on a "Go Online" button on the toaster that appears after clicking on the instant messaging icon. I'll attach a screenshot.
It's been crashing every time I do that. It also crashes while logging in through other ways, though less consistently so. I'll attach another traceback if there's any changes on it.
Plasma shell panels go away for a few seconds and then get back running without furter issues; KDE and Plasma instant messaging features work as if nothing ever happened.

I've found a bunch of correlations between the stacks of some of the threads here and the ones at 348653, which is quite similar:
#0 read() at Thread 16 at 348653 <-> Thread 11 here
#0 poll() at Thread 15 at 348653 <->> Thread 4 here
#0 g_mutex_unlock at Thread 14 at 348653 <-> Thread 5 here, if g_main_context_prepare ≃ g_main_context_check
#0 g_mutex_unlock at Thread 35 at 348653 <-> Thread 6 here, if g_main_context_prepare ≃ g_main_context_check
#0 pthread_cond_wait at Thread 27,36  <-> Threads 14, 15 here

- Custom settings of the application:
I've got a bunch of widgets running, though not too many. I'm currenlty logged in to g66gle account.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
