Can we get a description how to reproduce this bug? I can reproduce 1988, but not this one. The patch does look good otherwise, but I would like to be able to test it.

@Tony: What Sugar version does the image you posted have?

[tonyforster]

version is OS140py

I don't know why the download stalled in the first place but I can replicate by commencing a download of turtleart mini from activities.sugarlabs.org and then unplugging the modem. The partially downloaded bundle cannot be deleted from the journal. (and it doesnt resume when connectivity is restored)

This is a dupe of #1876.

Looks good, please go ahead.
