Images on the picker failing to load / freezing the app

[mzorz]

I’m not sure what’s up with the top three thumbnails… the ones that are solid grey. It looks like it might be something that is failing to load?

I tried to use one of those when making a story to see what would happen and it ended up freezing the app.

Been able to reproduce when first installing the app and giving permissions, - it shows some greyed out items in the media picker. Then picking one of the greyed out thumbnails ended up crashing WPAndroid with this stacktrace:

Okay I was able to single out these greyed out files as being the ones that are captured and saved with the Stories library capture mode itself, after a re-install.

Steps to reproduce:

1. install WPAndroid, log in, create a story by capturing a couple of pictures with stories capture mode
2. save the story (publish)
3. now go to media section and tap + to add
4. observe the newly created slide can be seen there
5. uninstall the app, and reinstall
6. log in to WPAndroid
7. go to media section and tap + to add
8. observe you can only see the pictures captured with other apps, but the ones captured with the Stories library are greyed out.
