The best place to ask programming/development questions, imo. UPDATE: stackoverflow is the *worst* place to *ask* questions (if your first question/comment doesn't get any up-rating/response, then u can't ask anymore questions--ridiculously unrealistic), but a great reference for finding answers.

debugging kxstudio-team's musescore package

I've just spent the last 3-4 hours trying to figure out how to report a bug for musescore and how to debug a musescore crash, but it looks like i can't do any debugging before kxstudio-team enables ddebs for their PAA.

below are my raw, personal notes, currently for my own use, while i await a reply from the kxstudio-team about enabling ddebs.
=====================

my original bug report:
http://musescore.org/en/node/21768

"
SUBJECT: "Define" keyboard shortcut in v1.3.5702 causes MuseScore to crash/close

I'm running musescore version 1.3 revision 5702 in Ubuntu Linux 13.04 64-bit. When I open musescore settings and try to define an unassigned keyboard shortcut by selecting a shortcut, then clicking the "Define" button, musescore crashes/closes.

UPDATE
I see I'm using the musescore package from this PPA:
http://ppa.launchpad.net/kxstudio-team/ppa/ubuntu/ raring/main amd64 Packages

packaged by the kxstudio-team:
https://launchpad.net/~kxstudio-team

the package is version 1.3+dfsg-1+nopulse1~raring1

and is available here:
http://ppa.launchpad.net/kxstudio-team/ppa/ubuntu/pool/main/m/musescore/musescore_1.3+dfsg-1+nopulse1~raring1_amd64.deb

I've asked them to enable ddebs for this package so I can provide debugging information for you to help you fix this bug easier. I'll add a comment/upload an attachment later when that is done, unless you're able to fix the issue without debugging info.

I don't know if the error is in the musescore code, or if it is due to a problem with kxstudio-team's compiling/packaging.

apt-cache policy musescore

gave this output:

sudo apt-get install musescore-dbgsym=1.3+dfsg-1+nopulse1~raring1

didn't work:

E: Version '1.3+dfsg-1+nopulse1~raring1' for 'musescore-dbgsym' was not found

sudo apt-get install musescore-dbgsym=1.2+dfsg-1

didn't work (wouldn't work bc this is the ubuntu package--an earlier version):

The following packages have unmet dependencies:
 musescore-dbgsym : Depends: musescore (= 1.2+dfsg-1) but 1.3+dfsg-1+nopulse1~raring1 is to be installed
E: Unable to correct problems, you have held broken packages.




THE PROBLEM IS THAT I AM USING kxstudio-team's VERSION OF MUSESCORE, BUT THEY DON'T PROVIDE ddebs/dbgsym files

my request to kxstudio-team:

SUBJECT: how do i post a bug? musescore 1.3+dfsg-1+nopulse1~raring1 crashes when editing keyboard shortcuts

can you please enable ddebs for musescore?

according to this post, your admins can do this:
https://bugs.launchpad.net/launchpad/+bug/156575/comments/21

"Launchpad admins can enable ddebs on a per-PPA basis. They are published in the PPA itself, alongside the normal debs."

I posted my original bug report to the musescore team here:
http://musescore.org/en/node/21768

but it would be nice to give them some debugging information to help them fix it faster.

thanks in advance,
nick humphrey
