if you don't (or forget to) attach a file extension to the destination name
mediawiki puts out the following error:
"." is not a recommended image file format.
that is a bit confusing, it should say something like this:
you did not attach a file extension to the destination name, please enter any to
upload your file.
ps: maybe you could check what file extension the selected file has and attach
it to the destination name?
Already fixed with r20100 (bug 8728)
