To be clear here, I asked @yml to open this issue because it came up in his testing and did not seem to be an error I my code as I don’t define any custom filter types (or use any filters at all) in wormhole-gui 🙂

[Jacalz]

My best guess is that the function is getting a nil filter and the else block in

fyne/internal/driver/gomobile/file.go

Line 40 in c29a062

fyne.LogError("Custom filter types not supported on mobile", nil)

flags that as not being a valid filter.

app crash with the following message logs

Are you certain the app crashed? That logged error should not be the cause of a crash.

flags that as not being a valid filter.

Agreed. But that should not cause a crash...

Indeed, certainly not. I guess we need to figure out what’s causing the crash. In the meantime, it looks like we squashed a little bug 🙂

Fixed as of fcad6b2. Closing this.
