We write new signal/slot system? like in QT.

Unittests works fine, but after trying using it in our test application, we encountered a strange problem.
des/import/des/app/sdlevproc.d(57): Error: function des.util.signal.signal.Signal!(Vector!(2LU, int, "x y")).Signal.opCall (Vector!(2LU, int, "x y")) is not callable using argument types (MouseEvent)
But, one can pass to this method only mouse events, and event, that take Vector!(2LU, int, "x y") is in another class definition, and has another name. And there are few more errors like this.

Finally compilation crashes with exit code -6:
dmd: class.c:859: virtual void ClassDeclaration::semantic(Scope*): Assertion `type->ty != Tclass || ((TypeClass *)type)->sym == this' failed.
FAIL .dub/build/application-debug-linux.posix-x86_64-dmd-9A2D5BEE385B6AEDFC08EE311E6172FC ftree executable

Test project:
https://github.com/deviator/fractaltree/tree/aea7ead22da7ffeaa55c9c74ef9e86b93bc60f8d

Does anyone has any suggestions about this issue?

This is an ICE (internal compiler error). ICE's are *always* compiler
bugs. Please file a critical bug on bugzilla (http://issues.dlang.org/).
