Also, it is a regression. It did not crash in 3.x.

So, I:

 - Extended the features of our firebird driver enough to support the
   reproduction case

 - Made a firebird (Java-free) reproduction case. Note that in my case
   some linguistic (Writer?) stuff wants to load Java anyway at
   startup, so I had to disable Java in the preferences (and refuse
   again to load it at the prompt at startup time) to make the run
   "truly" Java-free.

 - Made a valgrind trace. This confirms my suspicion that this is a
   "use after free()", and shows us the backtrace that did the free();
   however that backtrace is again completely within sfx2, vcl,
   ... again leaving me rather clueless.

Anybody feeling like they could be our hero?
