Jenkins workspace cleanup misses Sikuli's .vlog.png files

Sometimes after a test job run, the workspace on the isotesters isn’t empty as it should be with the Workspace Cleanup Jenkins plugin we’re using. It happens that one can find quite a few (but not always the same number) of files in the form of:

This is a bit annoying, because after a while it tends to grow and take too much room in the partition, and make test jobs failing because they can’t fetch the ISO they need.

This seems related to Sikuli, which creates that kind of files in it’s logging code

It’s difficult to get when this happens, but could be when a test job is aborted and sikuli is killed maybe.

I guess a good quick workaround would be to set up a cronjob that deletes once in a while that kind of files.
