New crash information added by DrKonqi

digikam (3.5.0) on KDE Platform 4.11.3 using Qt 4.8.5

- What I was doing when the application crashed:

Manually changing face tags in pictures, e.g. changing a picture where a person
has been erroneously tagged as "Alice" to the proper tag "Bob".

It suffices to change only one tag in only one picture. After some twenty
seconds, Digikam starts eating up memory. Without any ulimit set, this will
make the computer completely unresponsive *until* it runs out of memory, and
Digikam gets killed/SIGSEGVed by the OS.

When setting an appropriate ulimit, Digikam crashes equally well, but at least
the computer stays responsive. :-/

- Unusual behavior I noticed:

Whenever I manually change a face tag in a picture, some ten or twenty seconds
later Digikam starts eating up all the virtual memory of the computer.
