Could be just a bad zim file?

[mgautierfr]

Without knowing the zim file it will be difficult to say :/
But the problem with the zim file we discovered recently should not be related to the suggestion search.

[kelson42]

What should be done next with this ticket?

[macgills]

we could re-visit https://github.com/kiwix/kiwix-android/issues/62 in which case this would surface as a more recoverable error app side

[stale]

This issue has been automatically marked as stale because it has not had recent activity. It will be now be reviewed manually. Thank you for your contributions.

[kelson42]

Considering that whole got handling suggestion has changed and the lack of debuging information. I think we should close this ticket and this if this will happen again.
