ERROR: QT module set to xim

[homerobse]

I had this error:

ERROR: /etc/environment sets QT_IM_MODULE to xim. Please edit the file and fix this.

I got rid of it by including the line unset QT_IM_MODULE before source "$ENVFILE"

I don't know if this overwrote any setting that should be useful. And in that case, how to undo that and still be able to do the fix for cedilla. Can you help me with this?
