Report to https://bugs.kde.org

If there are two different defects please report two bugs to make it possible to properly track, thank you.

As far as I can tell they are the same bug.  I was doing the same thing, switching to data view, when the crash occurred.  It's happened more than once but I cannot cause it to crash on demand.

One is for forms the other is for tables. These are different things, different code, and your backtraces look different.

Anyway, for further testing, please temporarily change the current widgets style from cleanlooks to, something other, e.g. Window and try again.

From command line you cam do that by simply executing:

kexi --style=windows

Waiting for more info...
