Openshot leaves processes running after File > New, quit.

[Colin Law]

Running Ubuntu 12.10 with
openshot 1.4.3-1 from openshot.developers ppa
melt 0.8.2-0ubuntu0~sunab~quantal1 from sunab/kdenlive-release ppa

To replicate (in Ubuntu)
Start openshot in a terminal
Start htop or similar in another terminal
A number of python openshot processes are started.
In openshot select File > New Project and Save Project
A few more openshot processes are started.
Close openshot (File > Quit)
Openshot closes but four python openshot processes are left attached to the terminal and the terminal does not return to the command prompt.

If I perform that same action from the Ubuntu launcher then the processes are left as orphans.

Terminal log attached.
Would openshot.debug file be useful?

HI,

Follow this FAQ, please.

After, you should update your version of MLT but for that, you should use (and desactive after) this testing PPA https://launchpad.net/~sunab/+archive/kdenlive-svn (Beware, it is a testing PPA). Read more here : https://answers.launchpad.net/openshot/+faq/1861

Think to desactive before/reactive after the stable Sunab PPA when you update. The both PPA are incompatible in the same time.

HI, I looked at the FAQ but I do not understand what it means when it says I have to put the file in the "model folder". Does it just mean that you want me to supply the information in the FAQ here? Sorry to be thick.

[Olivier Girard (eolinwen)]

Okay, I have modified the FAQ at this level. It is something that I haven't think. :-(
This trick is only for experimented users who want to help us to improve/debug Openshot. Put just the model here completed. Like this I will have more informations to understand more quickly where is your problem (and resolve it too).

[Colin Law (colin-law)]

OK, I understand. Model file attached.

[Colin Law (colin-law)]

I have now tried with ppa:sunab/kdenlive-svn and the problem is unchanged.

[Olivier Girard (eolinwen)]

I've tried and I can't reproduce it.
I have been impressive by numbers of process launched and not only by Openshot (Firefox : a enormous number, 7 for Openshot, 6 for Radio Tray,...).
AFter closing, all process for OS are closed.
I am on Precise and see my model file attached for more information

I have a machine with Precise, I will install on there and see if I see the problem.
Did it start several more processes when you did File > New Project and Save?

[Colin Law (colin-law)]

I have checked with Precise on a different PC (but 32 bit, yours is 64 bit I see) and I still see the problem, which I find surprising. I have not got a 64 bit installation to try it on. Are you running Unity?

When I say File > New Project it replaces the current project with the new one. Is that correct or should I then have two project windows? I particularly notice that if I open an existing project, make a change but do not save it, and then open a new project, save and quit, that I do not get warned about closing the first project without saving it, which makes me wonder whether it is the first projects threads that are getting left running.

Yes.

On Unity, you have a nasty bug. i.e. If you have created several projects, When you select one (not the last), it will be always the last which will be opened. This issue touches not only Openshot but Inkscape, Dia,......

But in practical experience, the new/open project replace the previous in the same windows.
You should have a Advertising box for save the project, always this one.

[Colin Law (colin-law)]

I definitely get no Save warning when I Open New Project after editing previous one, so that suggests it is those threads that are stalled. I have checked carefully that the warning dialog is not hidden under other windows and it is not there.
I will download Precise 64 bit, hopefully I can run it from the live CD without installing it and will see if it works ok for me then.

[Olivier Girard (eolinwen)]

Normally you should have the same that if you close Openshot.

[Olivier Girard (eolinwen)]

I've checked and I must said you have reason. No Warning Dialog. Strange I have always believe that one was present. Something more to add.

[Olivier Girard (eolinwen)]

Could you open a bug report about this subject ?
Thanks.

[Colin Law (colin-law)]

Bug #1116167 opened

[Colin Law (colin-law)]

@Cenwen I have installed Ubuntu Precise 64 bits and openshot with the openshot.developers and kdenlive-release ppas and still see the hanging threads. Can you confirm that if you run openshot from a terminal then File > New Project, Save and File Quit that control returns to the terminal?

If it does then any suggestions what the difference may be between your setup and mine?

[Olivier Girard (eolinwen)]

I've do a go at this one now.
run Openshot around 10 processus, import a file, save it.
I quit and just 3 processus.
I don't know if you have the same thing.

>>If it does then any suggestions what the difference may be between your setup and mine?
I have unfortunately none. I don't see the difference and why this one.

[Colin Law (colin-law)]

I am not importing a file, the procedure is
Start Openshot from a terminal
File > New Project and Save
File > Quit
Several processes are left running and control does not return to the terminal.

What did you mean when you said "I Quit and just 3 processes"?

I hope that more clear now.

Effectively, we can't have the prompt in the terminal after to quit OS.
