Segfault on Character::wieldDropped

[Erik Ogenvik]

With a recently built cyphesis (1 month old perhaps) I got a segfault with this backtrace:
#0 Character::wieldDropped (this=0xa6bb420) at ../../rulesets/Character.cpp:213

warning: Source file is more recent than executable.

213 wield->setTo(getId());
