Referencer opens all PDFs in GIMP after Adobe Reader is installed and removed

[sebastian]

To reproduce the bug do the following. First, start with a system with no Adobe Reader and install Referencer. At this point if you're in Ubuntu/Gnome, Referencer would open all PDFs in Evince. Now install Adobe Reader from the repository. Just like the rest of the system, Referencer now opens all PDFs in Adobe. Now remove Adobe Reader (Ubuntu reverts to Gimp at this point) and make sure the default for opening PDFs in the system is Evince again. Now if you open a PDF in the file manager, it will open in evince, whereas Referencer will open it in Gimp. This is very annoying. If anyone knows of a workaround, please let me know.

OK, I did an strace and found that Referencer uses the file /usr/share/applications/defaults.list to find out what is the default application that opens a certain file type. Adding application/pdf=evince.desktop line to the above file made Referencer open the PDFs with Evince once again.

I have some more info on this. If you change locale to pl_PL it will stop opening pdf-s at all and if you switch to C locale it will open it in gedit. I belive this is a wrong method for handler selection. I belive it should use xdg-open to open the file. This is very inconvinient. One of the strengths of referencer was easy access to files. Now it is gone...

I forgot. This is karmic beta and referencer 1.1.5

This bug is actually caused by gnome-vfs. To be more precise, gnome-vfs doesn't respect the user settings but selects the first entry in /usr/share/applications/defaults.list. Since gnome-vfs is officially deprecated I guess this will not change anymore.

I prepared a patch which is using GIO instead of gnome-vfs for opening files. GIO is the replacement for gnome-vfs.

I've started doing some work done on GIo port as well. It's a long one and not as easy as the GtkBuilder port.

Mads, are you working on this? I can provide a patch with the work I've done so far in a few days.

[Mads Chr. Olesen (shiyee)]

Antonio: Yes, I have.
All my changes are in https://code.launchpad.net/~referencer-devs/referencer/shiyee_andrease_changes
I believe I've fixed this particular bug, there should be a commit in my branch with a reference to it.
(The bugs I have fixed I have set as "In progress" and assigned to me)

[Mads Chr. Olesen (shiyee)]

I have however not completed the port to GIO, so please feel free to work on that :-)

[António Lima (amrlima)]

Ok then, I'll continue the port on top of your work.

There's a bug about that I think.

[Mads Chr. Olesen (shiyee)]

Antonio: If you could create a branch and push your changes often, that would be great. Then we can avoid working on the same areas.

[António Lima (amrlima)]

I'll do that then. I'm very familiar with bazaar yet but I'll look into creating a branch here.

[António Lima (amrlima)]

I'm *not* very familiar ;)

Quick intro: http://doc.bazaar.canonical.com/latest/en/mini-tutorial/

#create local branch
bzr branch lp:~referencer-developers/shiyee_andrease_changes/

# hack hack hack

#commit locally, any number of times
bzr commit

#push changes to your own branch
bzr push lp:~referencer-developers/amrlima_gio_port/

Also, "bzr vis" is a really nice gui (requires the bzr-gtk package)

[Mads Chr. Olesen (shiyee)]

Oh sorry, "~referencer-developers "should be "~referencer-devs".

[António Lima (amrlima)]

Here it is!

Thanks! That was easy :)
