Hi,

I did some more tracing about the strange bug with latest kbabel
on my machine.
When I try to load a file, the program crashes when the progress
bar reaches 100%.

mb at lfs:~> gdb kbabel
GNU gdb 5.2.1

This GDB was configured as "i686-pc-linux-gnu"...
(gdb) run --nofork

- -g is not enabled, so bt doesn't give much info.


kbabeldict/modules/dbsearchengine/database.cpp
void  DataBaseManager::loadInfo()  
{
 int nrec;
 DB_BTREE_STAT *stat;
// memset(&stat,0,sizeof(DB_BTREE_STAT));
 if(infoDb->stat(infoDb,&stat,DB_FAST_STAT))
  fprintf(stderr,"Cannot stat\n");
 nrec=stat->bt_nkeys;
free(stat);

 info.clear();
 for(int i=1;i<=nrec;i++)     // I think DB2 Recno are 1 based.
  { 
  info.append(getCatalogInfo(i));
  }

}

Here should be the point to start.
Why does the stat() fail?

Please CC: me, as I'm not on the list.
