klangfalter isn't able to reload configuration

[Houston4444]

OS: KXstudio 64bits (tested on kubuntu 15.04 and 14.04, with kxstudio repos)

Maybe it's a compilation bug.
Klangfalter is working fine but when I reload my session (tested on Carla and Ardour4) the wave form doesn't appear. It looks like that :

And Plugin don't works. "Dry" is still here, and it sounds, but "wet" is absent and doesn't sound. If I change sound file, Label under wave form place change, but "wet" is still absent.
The only one solution is to remove plugin and add a Klangfalter plugin again.

I've seen this happening sometimes, but I was never able to get a set of actions that caused this.
Right now for you it's just only saving and reloading the project, and the bug is present?

(any details on how I can reproduce this are welcome. ie, jack settings etc)

On my two computers, it always happens.
I don't think it comes from jack settings but my config is:
ALSA soundcard
SampleRate: 44100
Buffer: 128
Periods/Buffer:2
Realtime
Realtime priority:10

I just tried with Carla on ALSA and bug is the same.

For example with Carla:
Open Carla
Add Klangfalter plugin (as LV2 or VST, bug is the same)
Load a sound file convolution
Save Carla project as klangtest.carxp
Close Carla
Open Carla
Load klangtest.carxp
Test Klangfalter

Bug is the same on Ardour4. On Qtractor this plugin don't seems to work very well.

Closed the following issue as duplicate of this one:
#10

I tried to reproduce this with Carla on Mac, but Carla crashed reproducibly on my machine when trying to scan for plugins, and I don't have a Linux system here at the moment.

I couldn't reproduce it on my Mac neither in Ableton Live nor in Cubase, so I'm afraid there's nothing I can do for now...

I think I'm hitting this bug, similar atleast, in Linux with the VST version.
For me it works reliably when opening on the same computer that created the project (this is with MusE as host)
but if I try to open the project on another computer, with the impulse response available at the same path, I get a dry instance of klangfalter. Meaning that the wave file is not loaded. The parameter settings are ok though.
