compiz crashed with SIGSEGV in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string() from unity::launcher::HudLauncherIcon::OnHudIconChanged()

Did this happen when you were typing in the hud, or when you just opened it?

Not sure. I don't use the HUD but do trigger it by accident sometimes.

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

Now that my crash is known to be a dupe, I can try to answer Bilal's question. I wasn't trying to use the HUD, and never saw it appear. I was switching windows with Ctrl-Alt-Tab, twice in a row, when compiz crashed. Perhaps the HUD started when it shouldn't (I don't have that bug number at hand), but I never perceived it.

Thanks.

The crash is in the copy ctor. But this line:

 std::string hud_icon_name = glib::Variant(data).GetString();

should call the ***move*** ctor. This is weird.

Andrea, probably it happens due to the temporary variable...
