cancel in-progress upload not working

[jacelo]

I tried to cancel an uploading file, and nothing happens. It gets stuck with the loading bar at 100%.

Sorry I couldn't help you back then. I'm trying to clean the issue list now.

If anybody else gets to see this, I think the "cancel" is only meant for files put into the upload "queue". They can be cancelled only before upload starts.
