[snap] Missing icon in indicator

Bug Description

Chromium is adding an appindicator, which has a missing icon when running from the snap. I've confirmed with the deb that it shows the chromium icon there. I'm not sure what setting makes it display the appindicator, I've had it there for years so must be some setting I have that is being synced.

The only extensions I have installer are:

  * The Great Suspender
  * Google Drive
  * Google Calendar

Same issue, with additional icon for Google Hangouts as well.

Chris, thanks for the confirmation. I haven't been able to observe the issue myself, can you share details on what shows that appindicator when using the chromium deb?

My best guess is:


Logs from running chromium in snap that indicate this is likely a problem:
(chrome:29051): libappindicator-WARNING **: 14:11:04.701: Using '/tmp' paths in SNAP environment will lead to unreadable resources


The (missing) icons in question are located for me at:

Is there an env variable we can set to change the location of tmp? I think in generally it shouldn't be attempting to use /tmp for anything.

Thanks Chris for those details.

AppIndicatorIcon::WriteUnityTempImageOnWorkerThread() calls base::CreateNewTempDirectory(), which calls GetTempDir() (in https://cs.chromium.org/chromium/src/base/files/file_util_posix.cc), which honours the TMPDIR environment variable.

So we need a way for chromium to share icons with the host's libappindicator. I'm pretty sure this has already been solved for other snaps, but I don't know how.

It looks like setting TMPDIR to $XDG_RUNTIME_DIR in snapcraft.yaml's environment section for the app should do the trick (thanks Trevinho for the hint!).

I've confirmed the fix works, thanks!

And I've confirmed on my end that the fix works too. Installing the Google Hangouts extension enables the appindicator icon.

The fix introduced a nasty regression (bug #1838508) and had to be reverted.
