Chromium Crashes When Triggering File Dialog

[Eray Erdin]

I've installed Chromium via Snap. Chromium seems to crash any time it triggers a native file dialog. This can be replicated by doing "Save file as", "Save image as" or simply doing CTRL+O to open a local web page.

I've launched it from the terminal to see if it has any prints. Here's what I've got *before* the crash:

```plain

This may indicate that pixbuf loaders or the mime database could not be found.
```

Here's what I've got *when* it crashed:

```plain
Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /snap/chromium/1506/data-dir/icons/Adwaita/16x16/status/image-missing.png: Unable to load image-loading module: /snap/chromium/1514/gnome-platform/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.so: /snap/chromium/1514/gnome-platform/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.so: cannot open shared object file: No such file or directory (gdk-pixbuf-error-quark, 5)

```

What is the issue here? How can I resolve this?

Seems like image-missing.png is missing and since Chromium is in a confined environment and they manage the dependencies, the issue cannot seem to be resolved. At least this is what I understood from the error message.

Huh, there's something wrong with the connections, all the plugs appear to be disconnected. I don't think the app should even start in this situation.

Can you try removing and re-installing the snap, then check whether the "snap connections chromium" command lists plugs as being connected to slots? At the very least the following plugs should be connected:

  chromium:browser-sandbox
  chromium:gnome-3-28-1804
  chromium:desktop
  chromium:network
  chromium:x11

I have uninstalled and reinstalled Chromium snap.

Running Chromium via the terminal gives
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.

Actually, I believe this is a different bug, so will open a separate issue.
