Bug Description

Binary package hint: unity

Got this when trying to unpin a launcher. Backtrace attached.

To reproduce:

* Copy /usr/share/applications/foo.desktop to ~/.local/share/applications (I used gcalctool)
* Start foo.desktop via the Ubuntu logo -> /usr/share/applications/
* Pin the running foo launcher and quit the application
=> the favorites now contain 'foo.desktop' (checked via gsettings get ...)
* Unpin the running foo launcher
=> Compiz crashes

The last messages I get on the console are:

** (<unknown>:12267): WARNING **: Unable to remove favorite '/usr/share/applications/gcalctool.desktop': Does not exist in favorites

(<unknown>:12267): GLib-CRITICAL **: g_variant_new_string: assertion `g_utf8_validate (string, -1, NULL)' failed

Before the crash (directly after pinning), the launcher starts /usr/share/applications/foo.desktop.

After the crash (or a Compiz restart) the launcher starts ~/.local/share/applications/foo.desktop instead (even though the favorites just show 'foo.desktop'). If that's the case I can unpin the launcher without a crash.

Also, pinning and unpinning ~/.local/share/applications/foo.desktop doesn't cause any issues.

Even if the backtrace is not complete (did you installed debug symbols for bamf and unity?), there are enough info to reproduce the crash. Thanks Hernando :)

I can reproduce the issue systematically with the konversation launcher. The trace is similar to Hernando's.
