SIGABRT in valac compiling unity-place-files

[Balló György]

I can't build Unity Files Place in Arch Linux due a vala compilation error. (Unity Applications Place was built fine.)
All dependences are installed correctly:
glib2 2.27.91
libzeitgeist 0.3.2
libunity 3.2.14
zeitgeist-extensions 0.0.6
vala 0.10.3 (I've also tried with 0.11.5)

The build log:
make all-recursive
make[1]: Entering directory `/home/ballogy/unity-place-files/src/unity-place-files-0.5.34'
Making all in src
make[2]: Entering directory `/home/ballogy/unity-place-files/src/unity-place-files-0.5.34/src'
  GEN unity_files_daemon.vala.stamp

So it appears that something in the stack doesn't support
GApplication... The glib version you have should be good enough, so
perhaps it's the case the Vala version is too old, but I have it
working ok with 0.11.3 and 0.11.5 here and you say that that doesn't
work.

What does the command 'grep Application
/usr/share/vala-0.12/vapi/gio-2.0.vapi' tell you? It oughta print out
something with "public class Application ...".

Second guessing; I think that maybe your 0.11.5 Vala compiler wasn't
correctly picked up at build time, and it used the old 0.10.3 one
instead without that being visible in the build log?

Finally I can built them with both 0.11.3 and 0.11.5 version. I have to apply this patch to vala (without them I always get an error): http://bazaar.launchpad.net/~ubuntu-desktop/vala/ubuntu/view/head:/debian/patches/02_dont_sigabrt_on_unknown_instance.patch

And version 0.10.3 is too old for build this package, so required vala version should be increased in configure.ac.

Ah, awesome György. I'm marking as invalid here since we really need this fix in upstream Vala. I think I submitted that Vala patch upstream a while ago, but maybe it got lost in the nether regions of Gnom's bugzilla :-)
