Fwd: Migration crash

Wed Aug 16 19:12:28 BST 2017

Interesting. I think this is basically the same problem that I fixed in
https://bugs.kde.org/show_bug.cgi?id=382732

I was wondering why this did not fix your issue with the latest AppImage
but having re-read am I correct that you are migrating from SQLite to
MySQL? If so then my fix ignores that particular use case.

The good news is that it should be fairly easy to adapt the 382732 to
work migrating from SQLite too.

Are you able/willing to share your existing SQLite database with me
privately so that I can work on this using some real, problematic data?
If you can then please email a compressed version to me or send me a
link to somewhere that I can download it.

Best Regards

Richard
