more segfaults (sqlite this time)

[Jan-Henrik Haukeland]

Actually, this one may be as simple as using va_list ap_copy in  
StringBuffer to ensure that the argument list is valid and guard  
against an off-by-one bug. I have checked in a new version to the  
repository and if you could test, that would be swell. Otherwise if  
you get this again, could you look closer at the StringBuffer memory  
buffer to see if it looks valid.
