did that, still crashes.

It did a "git disect" thing.
I conclude that commit 2036e227488ff7c2a2a811286b3cf8ebb4db1005
is where the crash starts when I double-click "Amp impulse".
(ie. for commit 55893198fbcf084e8ca5fd6364fec9367caed142 there is
no crash and for commit 2036e227488ff7c2a2a811286b3cf8ebb4db1005
there is a crash)

I don't know where to go from there, it's all in c++ and I don't
know that language very well.

I did, still crashes, so it's not related.

atk is at 2.10.0 here.

Here are versions of some software I installed:
atkmm-2.22.6.tar.xz
boost_1_53_0.7z
cairomm-1.10.0.tar.gz
eigen3-3.2.0.tar.bz2
fftw-3.3.3.tar.gz
glibmm-2.36.2.tar.xz
gtkmm-2.24.3.tar.xz
jack-1.9.9.5.tar.bz2
libsamplerate-0.1.8.tar.gz
libsigc++-2.3.1.tar.xz
libxml2-2.9.1.tar.gz
lv2-1.4.0.tar.bz2
pangomm-2.28.4.tar.bz2
raptor2-2.0.9.tar.gz

 From debian, I have:
gtk+2.0 2.24.21
atk     2.10.0
pango   1.32.5
cairo   1.12.16

If it's not too hard for you, can you tell me the versions
of those software that you have?

I also see that double-clicking L/H/Filter crashes even for
guitarix 0.27.1.
I didn't check earlier versions. I will. Maybe it is related in
some way and since the code is older, things might be simpler
to understand.

Hell, I just wanted to have some fun with the electric guitar :)
