Segmentation fault when the application closes

[PerfectCarl]

I just played with the app after a first time install : opening and closing it.
The app segfault each time I close it.

For some reason, apport doesn't open midori to post a new bug.

Hi! Is this problem still happening? If it is, will you please run Vocal from terminal and copy/paste any output that you see? I'm unable to reproduce it on my machines.

Thanks!

I swear I did, but for some reason launchpad ate it.
I'm using freya 64bits
Here's the console log:

Note: there is also FATAL warnings at the start of the app that don't look too nice, too.

Because I'm a nice guy, I built a debug version of vocal to get a full stacktrace :

To reproduce the bug, uninstall vocal, make sure no podcast has been added.
Then open the app and close it immediately.

Oh, wow! Thanks! I was able to reproduce. I'll work on a fix right now.
