Is it right to assume in 'gb.qt.kde.html.so' is something wrong?

Uhmm 
/usr/local/lib/gambas2/gb.qt.kde.html.so
what if I add some mesages?
cd source/main/src/gbc/gbi.c

...

	include = lt_dlsym(lib, LIB_INCLUDE);

analyze_native_component is called in 
  static void analyze(const char *comp, bool include)

  placing in this function anywhere 'fprintf(stderr, "analize: %s\n", path);'

 ??? not called 'analyze_native_component(const char *path)' anymore?
