search crashes wingpanel

[Jonas Bulik]

I am using the ElementaryOS 0.4 Loki Beta 64bit.

I tried to remove the desktop entries for fcitx from the app view but now when I try to use the search wingpanel restarts. I managed to fix it by removing all these files:

~/.local/share/applications/fcitx-config-gtk3.desktop
~/.local/share/applications/fcitx-configtool.desktop
~/.local/share/applications/fcitx-qimpanel-configtool.desktop
~/.local/share/applications/fcitx-skin-installer.desktop
~/.local/share/applications/fcitx.desktop

Sadly I didn't save them so I can't get you the contents of them.
I first tried to delete the entries with alacarte though, maybe that helps.
Here is also the debug log:

If you tell me where I can find a traceback file or something, I'd be glad to provide it.
If you need more info about my system, just ask.

Sorry, we can't reproduce this issue, the file you provided on G+ does not cause any issue for me, we can't solve it until you provide the contents of removed files, or someone will have the same issue or figure out where it exists in the code.

If it can help, I had the same issue yesterday when updating IntelliJ from 2016.2 to 2016.3. The all IDE is in one folder and after I deleted it I searched for "idea" in slingshot, it crashed, but it was smart enought to restart and remove the intelliJ entry.
Slingshot shouldn't crash because file are missing.

[Eric Karnes (eric-karnes1)]

Just tracked down this issue so I can explain what's happening, at least in my case. Wingpanel/Slingshot were crashing because I had copied some .desktop files from /usr/share/application over to .local/share/applications and had added "Hidden=true". I couldn't reproduce this with a generic .desktop file just in .local/share/applications so I assume it's just an issue with the same desktop file being in both locations but with the .local/share/applications one containing "Hidden=true".

[Eric Karnes (eric-karnes1)]

Since this bug is about to expire I'm going to change it from incomplete to confirmed since I can verify this is an actual bug and I can reproduce it.

[Alexander Maiburg (80995-maiburg)]

In my case the file vim.desktop caused this error. Removing it from ~/.local/share/applications fixed it. See attached file.
