--- Comment #19 from Torsten Enderling <carfesh at gmx.net> ---
I found an interesting article discussing some limits regarding malloc:
http://forums.codeguru.com/showthread.php?threadid=518947

I can see in Process Monitor that the virtual size of digiKam is about 1,8 GB
when that call fails (once the GUI starts, digiKam seems to pull obscene
amounts of virtual memory), so it may be that you are reaching the limit of the
2 GB _virtual_ memory size, or that that 2GB space doesn't have enough
unfragmented free space for 39MB. 

Physical memory usage of digiKam is just about 110MB however, but that memory
usage looks kind of weird. The only other application I have running with that
kind of virtual memory size is a SQL server express installation. Is it
possible there is a memory leak somewhere?

Since I'm on a 64 bit system, it might help a little bit to compile the
application as large address aware to counter that I suppose.

The database is just 20MB in size, so I don't think it's the database itself
being kept in memory that is taking up so much.
