Not happening here, albeit with sddm.

I'll guess it may be a DM problem.

I did a clean network install around 8 pm yesterday and problem still there
picking just xfce DM during install and selecting all other package groups
during custom install.

I will assign this to maintainer 'wally" when I work that out...
In the meantime, I will check it out with M7 betas 2 & (need to install it) 3.

I would be surprised if it is a *display manager* problem; I suspect we are talking *desktops*. You indicated Xfce; Frank did not say.

Hm, I assumed a multi-DM/DE install by Frank who tested in an xfce DE user
account under sddm DM.

No, sorry, this was with Plasma.

Full bt with gdb would be nice.
Comment 10 Lewis Smith 2019-04-13 10:55:36 CEST
M7beta3 real hardware, xfburn-0.5.5-3.mga7

Just some confirmations:
- The crash does *not* happen from "Audio CD" which follows the same dialogue path as the bugged "New Data Composition".
- It has nothing to do with display managers or desktops. I have reproduced it in the following combinations:
 GDM: Gnome, Cinnamon, Xfce
 LightDM: LXDE, Xfce
 LXDM: LXDE, Xfce
 SDDM: Plasma, Xfce

Would you like to say "How?" for those of us not clued up?

Going to need some very exacting steps for the above request.
Hopefully you are not requiring a compile/link to get traceback/symbols and
whatnot.

1. Enable debug media
2. Do 'debuginfo-install xfburn-0.5.5-3.mga7.x86_64'
3. Start xfburn with gdb

Commands/steps are not very exact or precise. :(

0. click up a root terminal
[root@wb ~]# 

1.  Enable debug media
-bash: Enable: command not found

2.  debuginfo-install xfburn-0.5.5-3.mga7.x86_64
No package named xfburn-debuginfo
Something went wrong, make sure your Debug media are configured properly

0. click up two root terminals

select root terminal 1

1. drakrpm-edit-media --expert
set Enable and Update check boxes for all Debug selections.

2. debuginfo-install xfburn-0.5.5-3.mga7.x86_64
 answer Y for displayed rpms

3. gdb $(type -p xfburn)
(gdb) run

   Continue pasting any additional debuginfo-install packages requests from
   terminal 1 into second root terminal. Upon competition, in terminal 1
(gdb) quit
    y
Hit up arrow to run step 3 again.
Run step 3 as many times as required to get all debuginfo-install requests installed.

After 171 rpm installed, I get a continue request for same package installs.
so here the resulting screen contents. I also tried the urpmi instructions
for build ids, all failed to find them.

Going to see how to remove all the debuginfo packages. and with my luck
will have to do another clean install.

Not so you would notice. Tried just xfburn pkg install. Failed.
Installed all packages from test with just 64 bit media and nonfree/tainted enabled.
As root, Ran 
  cd ~bittwister/.config/
  \rm -r Thunar xfburn xfce4
re-booted system, tried as root and bittwister
Still failed.

$ xfburn

This is for a Data Compilation.

Funny enough - if I try to do an audio burn it seems to work.
Comment 18 Brian Rockwell 2019-08-24 21:03:08 CEST
Another odd behavior.

If I drag and drop files into the data compilation it will work.

It is when I click the Add button and add from the pop-up file list that it segfaults.

An upstream bug report about the issue and findings would be nice.
