Hello list,
I currently testing 2.4.44+dfsg-1 from the git repository (wich I urgently need),
but experience occasional segfaults:
Program received signal SIGSEGV, Segmentation fault.

It seems that queries that return large amounts of data (i.e. including jpegPhoto attributes) will trigger this segfault.
