FYI, apparently KTechLab 0.51.0 might crash when using subcircuits. Release 0.50.0 is not affected. Fix is in git master [1] Testing is welcome :-)
The crash is introduced by the modernistaion of signals/slots mechanism, where a C++ lambda has been introduced, and I assume that those changes interfere with some object lifetime.

This started happening this week, it was working without problems before. This only happens with custom subcircuits and not the default ones.

Create a custom sub circuit. 2. Add it to another circuit. OBSERVED RESULT Program crashes with sigfault. EXPECTED RESULT Use subcircuit without problems.
