Comment (by apedog):

 I'd like to start off by saying that this is not a major issue for me. I
 ran across this edge-case and figured I'd post a bug report - for the
 record. This did not impede my work in any meaningful way. Maybe it's an
 unimportant edge-case, maybe it touches upon a deeper implementation
 problem - I honestly don't know.

 Nonetheless, if this issue is to be addressed:
 1. At the very least the message "Could not delete old plugin" is wrong.
 The old plugin ''was'' deleted. Empty plugin directory was all that
 remained.

 2. As for "expected" behaviour - my expectation would be that if the
 update failed, I'd still have the old version in place, and not have the
 plugin vanish unceremoniously. Or at least some indication that a plugin
 was removed due to an error (and what the plugin's basename was - allowing
 the user to troubleshoot). As it stands upon Plugins page refresh -
 everything appears normal sans the deleted plugin.

 I've no idea as to the amount of work that would go into fixing this. Just
 laying it out.
