noise crashes on start (core dumped)

[Richard]

Well, I just compiled kernel 3.12.6 liquorix today, and Noise just crashed when starting it. I was previously using 3.12.5 liquorix, and Noise was working perfectly. At home, my eOS have the exactly same configuration and is working (AFAIK).

PS: I'm also using the latest stable release of fglrx.

Here's the gdb output:

Please, let me know if any other information is needed. Other audio programs are working as expected.

Best regards,
Richard.

Thanks Cole. I tested Noise yesterday with this same kernel / driver (same .config file, same patches on fglrx) configuration at home, and it worked properly. Only the hardware is different - like the audio device.

Best regards,
Richard.

[Richard (rkuesters)]

Update: I have just compiled the new beta AMD driver for Linux (released on 2014-01-08) and the bug still persists. Running "run -a" in gdb shows the about screen, though. Kinda weird, I'll try to compile it later based on the libc provided by the liquorix kernel to see if it runs.

[Richard (rkuesters)]

Update II: Just compiled noise from source (apt-get source noise), compiled and made it work without any problems -- except the missing 'path-string' key in dconf, which was easy to workaround:

$ GSETTINGS_SCHEMA_DIR=/opt/noise/share/glib-2.0/schemas/ ./noise
[_LOG_LEVEL_INFO 11:01:09.980346] Application.vala:77: Music version: 0.2.4
[_LOG_LEVEL_INFO 11:01:09.980386] Application.vala:79: Kernel version: 3.12.6-zen-20140107

But, when I try to use the schema I just created with the current installed noise, I got a core dump, but a different one:

$ GSETTINGS_SCHEMA_DIR=/opt/noise/share/glib-2.0/schemas/ noise
[_LOG_LEVEL_INFO 11:03:23.754240] Application.vala:77: Music version: 0.2
[_LOG_LEVEL_INFO 11:03:23.754280] Application.vala:79: Kernel version: 3.12.6-zen-20140107
[_LOG_LEVEL_WARN 11:03:23.758110] [GLib-GIO] Settings schema 'org.pantheon.noise.settings' does not contain a key named 'plugins-enabled'
Trace/breakpoint trap (core dumped)

And, for my surprise, 'plugins-enabled' key changed to 'plugins-disabled'. I just don't understand why :)

$ cat org.pantheon.noise.gschema.xml | grep plugins
    <key type="as" name="plugins-disabled">
    ...

After re-adding 'plugins-enabled' key to the schema XML and compiling it, (the installed) noise crashes again as described earlier.

Best regards,
Richard.

Sorry, but update III: re-generating the deb package from source (dpkg-buildpackage -us -uc -nc) and then installing the generated debs made it work again, as expected.

[Cole (morgenman)]

hmm I have not built this yet, (my dev machine is down right now), I experienced this error from the deb on the elemetary os ppa (stable). Which edits to the source code did you make for the final build? (the one which worked).

[Richard (rkuesters)]

Hello Cole.

I did not made any changes to the source code. Just downloaded 0.2.4 (which was the source from 0.2.0, strange), recompiled it and installed it. Nothing else, it just started working.

I think it maybe because I have the x-swat ppa enabled, but didn't tested it without the ppa.

Best regards,
Richard.

[Cole (morgenman)]

I tried it with x-swat but to no avail. I will use Beatbox until this is fixed.. Thanks!

[Richard (rkuesters)]

Well, I don't think this needs a fix, since version 0.2.4 is working without any modifications - recompiled or from repositories. Probably this was fixed in between, or the 0.2.0 version was compiled against a buggy lib or something. Don't know for sure.

[Cole (morgenman)]

this is still not working on my machine, version 0.2.4 r518 with no modifications, running luna ....12.04 ... is it just me?

[Richard (rkuesters)]

Have you tried compiling it from source and running just the binary? That was my first clue. I'm also in 12.04 Ubuntu (which Luna is based), using a customized Liquorix kernel (now on version 3.12.9) and noise, at least, opens properly. The only problem with compiling Noise myself was that it doesn't scan my folders for music. I had to change my music folder using dconf BEFORE launching it, and now it is working as a whole.

Indeed, very, very weird ...

[Cole (morgenman)]

Downgrade Libgranite1 to 0.2.2~r602-0+pkg53+r1~precise1 and it will work!
:D
so happy right now for figuring it out, can somebody verify?
