Nautilus quicklist includes erroneous entries related to file transactions

[Ari]

## Description

Sometimes the Nautilus quicklist will show items that shouldn't be there:

As you can see in the screenshot there are file transaction entries in the quicklist of the launcher. That would give you the impression that a file transaction is in progress. In fact, however, there isn't. Clicking the "Show Copy Dialog" entry will display an empty window without window controls. The other entry doesn't do anything.

## Steps to reproduce

What happens, as far as I can tell, is that these quicklist items will stick after completing a file transaction. So in order to reproduce this bug you will have to:

1. Make sure that Plank and Nautilus are running and that the Nautilus quicklist is displayed properly
2. Copy some files with Nautilus to another location in your file system. The quicklist should now have the extra entries.
3. After the file transaction is complete check back with the launcher and see if the entries are still there.

Shouldn't happen with r905 which reverted some bits which are responsible for it to show up while nautilus isn't showing a window.

[Ari (ari-lp)]

I have just installed r905. Unfortunately the issue persists. However, you should note that this bug wasn't introduced with r904. I have been observing this problem for a while and over several different revisions and only now I reported it.

Status changed to 'Confirmed' because the bug affects multiple users.
