[apport] scim-launcher crashed with SIGSEGV in QTextCodec::mimeName()

Binary package hint: scim

Crashes on login. I have made some modifications to X11 login scripts - the following is run before /etc/X11/Xsession.d/99x11-common_start:

export XMODIFIERS=@im=SCIM
export XMODIFIER=@im=SCIM
export GTK_IM_MODULE=scim
export QT_IM_MODULE=scim
export LANG='en_US.UTF-8'

scim -d
setxkbmap -model pc105 -layout us -variant basic
