The last Qtractor's version where I can open Klangfalter's GUI (e.g. to load impulse responses) is 3822. Something must have happened regarding lv2 modules' GUI handling. Trying to open Klangfalter's GUI in 3834 crashes Qtracor.
There is another difference to older versions. Don't know if it could be related: In 3834 the button for adding plugins in a track is grayed-out.

re. Klangfalter GUI crashes Qtractor:
may you point me to repository where i can find this plugin's lv2 source code and try to reproduce the issue?
meanwhile can you list or attach here the plugins lv2 manifest (.ttl) or just the output of lv2info plugin-uri ?
re. grayed out plugin add button:
fixed on svn trunk [r3835], thanks.
Klangfalter is found in DISTRHO:
svn co https://github.com/DISTRHO/DISTRHO.git
vi ports/Makefile <- delete everything with "cabbage" in its name
The plugin is in bin/lv2/KlangFalter.lv2
Output of lv2info https://github.com/HiFi-LoFi/KlangFalter is attached
A compiled version on a 64 Bit Xubuntu 12.04 is attached. Maybe it works on your system.
thanks for the pointers. tested with git://distrho.git.sf.net/gitroot/distrho/distrho though. after all it wasn't exclusive to klangfalter anyway, it could happen with any lv2 gui. the juced ones are just heavier, tanking longer to open up and to close down, exposing plenty of racier conditions that others don't ;)
maybe fixed on svn trunk [r3837] aka. qtractor 0.6.1.6+
please test && tell
Unfortunately it still crashes.
please rebuild and run for capturing a gdb stacktrace (./configure --enable-debug) which should tell you where, how and when exactly it is crashing.
i was experiencing random crashes on session close/new where it doesn't anymore. yours might be yet another problem, unrelated to what was fixed then
I attach a log where I first load a session and then try to open klangfalter's GUI.
