Could you check the source code if these packages crash while messing
with C++ exceptions? I just had a quick look into the menu package and
it seems that C++ exception handling is broken on mips using g++-2.95.4. 
A testcase like:

#include <iostream.h>
#include <string>

class ferror_open {
	int a;
public:
  ferror_open():a(2){};
  int message(){
    return a;
  };
};

int main()
{
	try {
		throw ferror_open();
	} catch(ferror_open d){ cout << d.message() << endl;};
}

causes a segfault while working as expected when using g++ 3.0.2. I don't
know how exceptions are implemented in g++. Some helpfull pointers are
*greatly* appreciated.  Should we try to fix this in 2.95.4 or switch to
3.0.2 for the affected packages?

P.S.: I'm cc'ing debian-gcc. Maybe we can get some helpfull pointers
from there.
