Qtractor crashes
Hi all, hi @rncbc. I've been working on a project for a few days, everything was coming along, then just about an hour ago, Qtractor started crashing whenever I would 1) try to change the fore/background color of a track to a custom color (clicking on the palette), or 2) normalizing an audio clip. I was originally running Qtractor under NSM with Raysession, but I have since tried both with and without with the same result.
I'm not sure what to look for...can somebody point me in the right direction to get started debugging this?

Re: Qtractor crashes
...it also crashes with a brand-new project, too.
I'm on Manjaro, and the Qtractor version is the one from the official Manjaro repo, v0.9.26-2.

Re: Qtractor crashes
Does it crash when you don a ballerini tutu and dance the last act of Swan Lake wearing a hockey mask like Jason in "Friday the 13th"?

Re: Qtractor crashes
I've had the same (sort of) prob problem w/ Qtractor. See this LM topic. Appeared to be incompatibility w/ XFCE. Workarounds:scott.thomason wrote: ↑Mon May 23, 2022 2:21 am Hi all, hi @rncbc.

- manually edit the .qtr file
- use another desktop environment to change colors

Re: Qtractor crashes
Thanks for the tip. I'll look into a non-Gnome/Gtk theme. I made sure I tested with the "Use desktop environment native dialogs" both on and off, and it crashes either way.Linuxmusician01 wrote: ↑Mon May 23, 2022 10:19 am I've had the same (sort of) prob problem w/ Qtractor.

While in View > Options, I unchecked the "Capture STDOUT" option, figuring that might allow any output to make it to the terminal, and it did:
Code: Select all
(process:60734): Gtk-CRITICAL **: 10:52:00.484: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed

Segmentation fault (core dumped)
Does this error give anyone more clues about what's going wrong?

Re: Qtractor crashes
not going into any meltdown whatsoever, but since gnome3 come along, its color picker is a dang nightmare for non-gtk2,3,4+ apps

Re: Qtractor crashes
Googling the error message "_gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed" lead me to a solution at https://forum.manjaro.org/t/qt5ct-crash ... e/81957/11. It solved the first problem, that of crashing when trying to open the color selector to change the color of a track. For the record, all I had to do was delete folder ~/.config/qt5ct, which also had the pleasant effect of getting rid of that dark theme.
However, I still get the crash when I try to normalize a .wav clip, and there is no output on the terminal besides the core dump message. Is there an environment variable or something I can set to get more info out of Qt perhaps?

Re: Qtractor crashes
Ah, I'll try a non-gtk theme just to prevent any future incompatibilities. For now, I've solved that issue by deleting ~/.config/qt5ct (and qt6ct for good measure).
Do you have any idea what might be causing the crash on normalize?

Re: Qtractor crashes
What kind of edits did you make to the .qtr file, and what impact did they have?Linuxmusician01 wrote: ↑Mon May 23, 2022 10:19 am I've had the same (sort of) prob problem w/ Qtractor. See this LM topic. Appeared to be incompatibility w/ XFCE. Workarounds:

What DE did you switch to for it to work?
Thanks...

Re: Qtractor crashes
Ah, I see the .qtr file is just XML. I can handle changing the colors there, and it will avoid changing Manjaro Gnome edition over to something Qt-ish. Thanks again.
