Crash : Internal error: pc 0x47 in read in psymtab, but not in symtab.

[tonnot]

I can view that the point that rise the error is located (every time at different point) inside a generic "ui_ui.h" that is a widget I create from main window.

(Internal error: pc 0x47 in read in psymtab, but not in symtab.)
(Internal error: pc 0x47 in read in psymtab, but not in symtab.)
(Internal error: pc 0x47 in read in psymtab, but not in symtab.)
(Internal error: pc 0x0 in read in psymtab, but not in symtab.)

Any idea about the origin of this error ?
Any idea about where I have to review my code?

NOTE: After disabled and re-enabled the calling function for this widget and two runs, all works fine again .....

Thanks
