Description Dennis Schridde 2018-09-21 06:48:57 UTC

Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.7-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

-- Information about the crash:
- What I was doing when the application crashed / unusual behavior I noticed:

1. I was experiencing internet connectivity problems (TCP connection attempts timing out, hostnames could not be resolved due to timeouts, etc)
2. Plasma hung for several minutes
3. After it recovered I logged out
4. It took Plasma a while to actually exit
5. On the next day I logged back in and found this crash report

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib64/libthread_db.so.1".

Comment 1 Friedrich W. H. Kossebau 2019-01-18 04:29:31 UTC

Thanks fro the report.

Seems the interesting point in the backtrace is

#30 0x00007fb082dc56ba in exit () from /lib64/libc.so.6

which is triggered from Qt's X backend class QXcbConnection, possibly because some state was reached where Qt's X handler could not cope with and just calls exit on the whole process.

Possibly Plasma might need improvements in doing the clean-up here, so the exit does not escalate in a crash. But more important would be to prevent the exit call. Which would need to know what Qt paniced about, no idea how to debug that myself.

Nothing to do with the weather dataengine itself from what I can tell, so moving over to Plasma Generic bugs.
