Public bug reported:
I downloaded Eclipse from here:
https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/kepler/SR2/eclipse-standard-kepler-SR2-linux-gtk-x86_64.tar.gz
which is a tar.gz, which I untarred into a custom folder, namely
~/Documents/programmi/eclipse, by placing the .tar.gz in ~/Documents/programmi
and right clicking on it with Nautilus and doing "extract here".
(~/Documents/programmi is not set up to be any special or privileged folder for
programs, it's just a folder that I created inside Documents).
Then I realized that was not the version of Eclipse I wanted, so I installed
Eclipsed by running in a terminal:
sudo apt-get install eclipse
This created, among other things, a /usr/share/applications/eclipse.desktop file
"which eclipse" outputs "/usr/bin/eclipse"
When I type "eclipse" into a terminal, the one installed with apt-get will run,
as expected.
I slightly modified /usr/share/applications/eclipse.desktop so that
UBUNTU_MENUPROXY would be used (to work around the menus-not-working bug), and
when I run "eclipse" from a terminal, I can see the menu is affected by the
change I made to the .desktop file, so the
/usr/share/applications/eclipse.desktop file somehow "relates" to the
executable that is run by writing just "eclipse" from a command line.
When I wrote "eclipse" into the Dash, the one I had manually downloaded
and unzipped would run, which is somewhat funny in itself, because I
wonder how it "finds" the one that I have installed in an arbitrary
folder and it doesn't find the one that has been installed with the
package manager.
Then I did the following:
- run "eclipse" from a terminal (this would run the apt-get installed one)
- right click on the icon on the launcher and choose "lock to launcher".
- exit eclipse
- click on the icon that has been created on the launcher
Expected: should run the same thing that was running when I locked it to the
launcher, which is what I run from a terminal typing "eclipse"
Observed: it runs the one that I had manually downloaded and unzipped.
Whatever is going on, there is an inconsistency here. If I run some
program, whatever I run it from, and then lock its icon to the launcher,
then clicking on that icon must load the program that was running when I
locked that icon on the launcher, whatever that is. Not some other
version that is installed somewhere else.
Then I deleted the folder ~/Documents/programmi/eclipse altogether. Now
the icon on the launcher does nothing. Even if I remove it (unlock from
launcher), start "eclipse" again from a terminal (which runs
/usr/bin/eclipse), lock it to the launcher again, exit it, even so when
I later click on the launcher icon it will launch nothing (as if
"looking for" the one that I deleted).
And surprisingly, when I type "eclipse" into the Dash, it still "finds"
the old one, or at least, it finds something that won't run if I click
on it. Even after restarting the computer.
The only file named eclipse.desktop in the entire filesystem is the one
under /usr/share/applications/eclipse.desktop
It's as if by merely unzipping the .tar.gz file into an arbitrary non-standard
folder, some kind of shortcut to it has been installed somewhere that allows it
to be found when typing "Eclipse" into the Dash; even if I didn't install any
package, just unzipped a .tar.gz file. Even after deleting the unzipped folder,
that "link" somehow persists somewhere. It's crazy. And it even takes the place
of the icon that I lock to Launcher when running /usr/bin/eclipse.
