[Digikam-devel] Memory corruption in svn head

[Craig Howard]

I'm seeing a crash caused by a detection of memory corruption.  I ran digikam 
in gdb and got the following backtrace.  I'm using gcc 4.0 on a debian 
unstable.  I've built all of kde from svn using kdesvn-build.  My digikam 
directory is on an NFS share and contains a few GB of images.
