With the latest fltk2 svn build (built using mingw / msys, gcc version
3.4.5), I'm getting a reproduce-able crash in fluid2, the chrash is in
the Browser code (although the issue comes from the Menu code I think).
If for instance, I load fluid2 and just click on the browser area where
no browser items are present, I get a segfault. The segfault appears to
be due to calling item()->selected() when there are no valid items in
the browser. The call to item() is returning NULL, but isn't being checked.
When I do a backtrace in gdb I get:
Program received signal SIGSEGV, Segmentation fault.
