The question is have you been opening/ trying to open any .exr files from maybe blender or some other graphics application?
I would say delete it but if you want to be over-careful, back it up first before deleting.
edit: this is what it says about the tmp file in gimprc
I have very occasionally found a stray remainder there, just delete it.

Quote:# Sets the folder for temporary storage. Files will appear here during the

# some files are likely to remain, so it is best if this folder not be one
# that is shared by other users. This is a single folder.
