The only way to check whether a file (a database in this case) is 
open from another program is to ask Finder through AppleScript or 
another program if the file-is-busy flag is set. On the other hand, 
Valentina should not crash but return system error that file is in 
use (code -31 if my memory doesn't fail me). It used to do that for 
sure, so I suggest you report this crash to Valentina's Mantis, so 
Ruslan's crew can look at it.
