Description Berend De Schouwer 2018-10-02 08:37:12 UTC

Description of problem:

Running gnome-music results in a python3.7 segfault (C segfault, not a python stacktrace)


Version-Release number of selected component (if applicable):

python3-3.7.0-9.fc29.x86_64


How reproducible:

Every time for me, but I suspect it's data dependent since gnome-music starts up and starts processing albums.


Steps to Reproduce:
1. start gnome-music
2. crash
3.

(debug on gnome-music indicates it processes +- 150 albums/mediaart -- not always the same.)


Actual results:

Python 3.7 segfault, like:
16988.900285] pool[18252]: segfault at 0 ip 0000000000000000 sp 00007f684eca2608 error 14 in python3.7[5645040a3000+1000]
[16988.900293] Code: Bad RIP value.


Expected results:

One of:
- gnome-music runs
- gnome-music creates a python stack trace


Additional info:

Abrt doesn't process correctly, so while I have files in /var/spool/abrt/, there's no automatic reporting right now in F29 Beta.

Comment 1 Charalampos Stratakis 2018-10-02 15:02:01 UTC

This seems more like a hardware or kernel issue. Changing it for now to gnome-music to see if the dev's have encountered that before.

Comment 2 Berend De Schouwer 2018-10-17 09:58:58 UTC

found part of the abrt problems, which trigger selinux faults, so I've entered bz #1640067

hopefully I'll eventually upload an actual python coredump

Comment 3 Berend De Schouwer 2018-10-17 10:07:37 UTC

manual backtrace currently results in:

Dwarf Error: could not find partial DIE containing offset 0x7d [in module /usr/lib/debug/usr/bin/python3.7-3.7.0-9.fc29.x86_64.debug]

Comment 4 Berend De Schouwer 2018-11-05 12:29:55 UTC

Fixed in gnome-music 3.30.2.

Dunno what fixed it, but it's fixed.
