onboard crashes on launch

Bug Description

I have a Lenovo with a touch screen.
When I launch Onboard, it crashes. It usually crashes on launch but I think there was one time where it didn't crash until I pressed the first key.
While I'm on the subject, could onboard be made a bit more user-friendly and simple? Like the iPad?

If you don't mind running non-release versions of Onboard, you might try the updated version available in our PPA:

By the way, the version in the PPA also includes two new layouts, that resemble more the layouts found on mobile devices.

I tried revision 1627 from the PPA (0.99.0+1627-0ppa~saucy1). I am running Kubuntu Saucy in VirtualBox. And it is crashing for me, too. The output from the terminal is:

gi._glib.GError: Unrecognized image file format

I don't know where I can find the log files - so I've written print(filename) in an appropiate place. The image file mentioned is /usr/share/onboard/layouts/images/erase.svg, I hope that helps.

Thanks for trying the PPA, Jörn.
You can get a debug log that shows the file names of loaded images with
$ onboard -ddebug
 but now that you found the file, I think I won't need this anymore.

Does this print anything?
$ /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders | grep -i svg

Does this make a difference?
$ sudo apt-get install librsvg2-common

Please attach that svg file /usr/share/onboard/layouts/images/erase.svg here.

It works now, with librsvg2-common - but I am not 100% sure, if that fixed it. If you want I can set up a VM tomorrow and check that. Just for the records, the erase.svg:

Yes, the missing librsvg2-common must have been the reason. That package wasn't on our radar before, but I see now we have only a suggest dependency via libgtk-3-0. I could imagine a fresh Kubuntu not having it. If you'd like to confirm this, yes please, try a new VM.
In any case, we better add that package as a direct dependency of Onboard.

I have double-checked that, librsvg2-common was the missing dependency.

Thank you, I've added the dependency and improved the error handling in trunk.
