Some programs can't see their own processes (read description)

[Nicholas Shatokhin]

For example, gedit. I can open files by double clicking on its in Nautilus. First file open gedit's window. Next files open new tabs in gedit's window. But if I open file from terminal after that (by gedit <filename>), gedit opens new window, not tab in existing window. And next files that opened from terminal creates tabs in new window (if I open files by clicking on it in Nautilus after that, its opens in tabs in previous window). If I open file from Gnome Commander, it opens third window. Why they all not opening in one window?

You can also do it by opening a first file (from nautilus), then moving the gedit window to an other workspace. After this, go back to the previous workspace, and open another file in the nautilus window. But I don't know if it is the required behaviour or not (it is useful if you want to work on 2 files together : launch 2 gedit windows and snap it to both sides).

(well, I just noticed that I can't reproduce exactly the bug you've reported, I have to switch to another workspace to open a second window. If I open one file from nautilus and one from the terminal in the same workspace, they go in the same window, in tabs. (this is on oneiric, with the lastest unity-shell))

If it's in different desktops it's good, bud if it the same desktop, file must opened in new tab.
