Bug ID: 383964
Summary: Going online on Instant Messaging Widget crashes
plasma
Product: plasmashell
Version: 5.10.4
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: raphly...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
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:
